With practice, you can quickly perform these calculations mentally and impress your friends with your newfound math skills!
Understanding Percentages and Fractions
When it comes to calculating percentages, having a solid understanding of fractions is essential. Percentages, as the name suggests, are essentially just another way to express fractions. They represent a portion or a part of a whole that is divided into 100 equal parts. Understanding how percentages and fractions relate to each other will make it much easier for you to calculate / as a percentage.
1.1 The Relationship Between Percentages and Fractions
Before diving into the calculations, it’s important to understand the relationship between percentages and fractions. A fraction is made up of two numbers – a numerator (top number) and a denominator (bottom number). The numerator represents the portion or part of the whole, while the denominator represents the total number of equal parts in that whole.
A percentage is just another way to express this fraction by converting it into parts per 100. To convert a fraction into a percentage, simply multiply its value by 100%. For example, if we have 3/4 as our fraction, then its equivalent percentage would be (3/4)*100% = 75%.
Likewise, we can also convert percentages back into fractions by dividing them by 100%. For instance, if we have 50%, its equivalent fraction would be (50/100) = 1/2. This means that 50% represents half or one out of every two equal parts.
1.2 Converting Fractions into Equivalent Forms
When working with percentages and fractions, it’s essential to know how to convert them into different forms while maintaining their equivalence. For example, you can convert any given fraction either in decimals or in percentages without changing its value.
To convert decimals into fractions or vice versa, divide them by their common multiple until there are no more decimal places left after division.
For example:
– To convert .5 = ?, divide both sides by .1, then you will get 5/10.
– Convert .75 = ?, divide both sides by .01 and simplify as 75/100=3/4.
1.3 How to Calculate / as a Percentage
Now that we understand the relationship between percentages and fractions and know how to convert them into different forms, let’s see how we can calculate / as a percentage using these concepts.
To calculate / as a percentage, follow these steps:
Step 1: Convert the fraction into decimal form (divide the numerator by the denominator).
Step 2: Multiply the decimal by 100% to get the equivalent percentage.
For example:
Let’s find out what is 20/25 expressed as a percentage?
Step 1: Converting fraction into decimal – dividing result in step two
20 ÷ 25 = .8
Step 2: Multiplying with % symbol
.8 *100% =80%
Therefore, 20/25 expressed as a percentage is equal to 80%.
By understanding the relationship between percentages and fractions and knowing how to
Step 1: Converting the fraction into a decimal.
Before we can calculate a fraction as a percentage, we must first convert the fraction into a decimal. This is because percentages are based on decimals, with 100% being equal to 1 whole or 1.00 in decimal form.
To convert a fraction into a decimal, we need to know the relationship between fractions and decimals. A fraction is simply a way of expressing a part-to-whole ratio, where the top number (numerator) represents the part and the bottom number (denominator) represents the whole.
For example, if we have the fraction 3/5, it means we have 3 parts out of a total of 5 parts. In decimal form, this would be expressed as 0.60 since when dividing 3 by 5, we get 0.60 as our answer.
Here are the steps to follow when converting fractions into decimals:
Step 1: Divide the numerator by the denominator.
To convert any fraction into a decimal, simply divide its numerator by its denominator using long division or use your calculator’s division function.
Let’s take another example using the fraction 7/8. We would divide 7 by 8 which gives us an answer of approximately .875 (or rounded off to .88). This means that our original fraction is equivalent to approximately .88 in decimal form.
Step2: Simplify (optional)
Sometimes you may end up with repeating numbers after dividing such as .33333… for one-third (1/3). In these cases, you can choose to round off your answer or simplify it even further if possible.
For example,
If you want to express four-sixths (4/6) as both simplified and in rounded-off form,
Option A: Simplified = two-thirds (.66666…) –> (.67)
Option B: Rounded = six-tenths (.6) –> (.60)
It is important to note that when converting a fraction into a decimal, the result may not always be an exact number. Due to the nature of decimals being infinite numbers, there may be some rounding involved when expressing it in decimal form.
In these cases, it is best to round off your answer to 2 or 3 decimal places for more accuracy depending on how precise you need your calculation to be.
By following these simple steps, you can easily convert any fraction into a decimal and continue with our next step of calculating it as a percentage. Stay tuned for our next section on how to calculate fractions as percentages using the newly converted decimal value.
Step 2: Multiplying the decimal by 100
Now that you have converted the fraction to a decimal in Step 1, it’s time to turn that decimal into a percentage. To do this, we will multiply the decimal by 100.
Why multiply by 100?
As we discussed in Step 1, percentages are ratios expressed out of 100. By multiplying the decimal by 100, we are essentially converting it into a ratio out of 100 and representing it as a percentage.
How to multiply decimals by 100?
To easily multiply any decimal number by 100, all you have to do is move the decimal point two places to the right. This means shifting all digits two places to the right and adding zeros if necessary.
For example:
0.38 x 100 = ____
If we move the decimal point two places to the right:
_ _ . _ _
We get:
38.00
Therefore, when we convert this back into a whole number, we get:
3800%
Looking at another example:
0.075 x 100 = ____
Moving the decimal point two places to the right gives us:
_ _ . _ _
And when we fill in zeros where necessary and convert back into a whole number:
7.50
This means that our original decimal of 0.075 is equivalent to
7.5%.
It’s important to note that when multiplying decimals by 100, there may be cases where rounding occurs due to limited space for numbers after multiplication. In these cases,it is generally acceptable and considered accurate enough for most applications.
Applying this step with fractions:
Sometimes you may come across an initial fraction instead of a decimal when trying to find a percentage.
In such cases,you’ll first need to follow step one (converting fractions into decimals) before moving on with step two
Let’s look at an example using a fraction:
3/5 x 100 = ____
First, we will convert the fraction to a decimal as shown in Step 1:
3/5 = 0.6
Now we can simply multiply this decimal by 100 and move the decimal point two places to the right:
60%
Congratulations, you have successfully converted a decimal into a percentage! Keep practicing with different numbers to solidify your understanding of this important step.
Pro tip: If you’re ever stuck on dividing decimals by 100, just remember that dividing by 100 is equivalent to multiplying by
` (one hundredth). For example,
0.75 ÷100 = ____
This can be rewritten as: 0.75 x ` (1/100)
Which gives us: 0.0075
So always keep in mind that dividing decimals by 100 is like shifting the decimal point two places to the left and adding zeros if needed.
In the next step, we will learn how to convert percentages back into fractions and decimals so you can easily switch between all three
Step 3: Adding the % Symbol
Once you have successfully divided your number by 100, it’s time to add the % symbol to your calculated percentage. This step may seem simple, but it is important in accurately representing your percentage value.
The % symbol is a shorthand for “per cent,” meaning “out of one hundred.” It is used to express a portion or ratio of something out of 100. When added to the end of a number, it indicates that the number is being shown as a percentage.
To add the % symbol to your calculated percentage, simply move the decimal point two places to the right and include the % sign at the end. For example, if you have calculated a percentage of 0.5, moving the decimal point two places to right would give you 50%, written as 50%.
It’s essential not to forget this critical step when calculating percentages as omitting or incorrectly placing the % symbol can change your final result significantly. For instance, if you mistakenly write 50 without adding the % sign, it will be interpreted as plain numbers and not percentages.
Furthermore, adding the % symbol also makes it easier for readers or viewers to understand that they are looking at a percentage value. It helps avoid any confusion or misinterpretation.
When dealing with fractions in which both numerator and denominator are multiples of ten (e.g., decreasing fractions), converting it into percentages becomes simpler and more intuitive—for example; if you have calculated a fraction such as $2/$10 using our guide in Step 1 and Step 2 resulting in an answer of $0.20 then converted into fractional form ($0/$10), all you need do now is proceed with Step 3: Adding The Percentage Sign by moving decimal points two steps eastwards resulting in becoming : (00)/10%=$200/100%=20%.
Adding the% symbol completes our calculation process and ensures that our percentage value is accurately represented, making it easier to understand and avoid any confusion. So make sure to remember this crucial step every time you calculate a percentage to ensure the accuracy of your results.
Example Calculation
1. Example Calculation
In this section, we will walk through a step-by-step example of how to calculate the percentage of one number compared to another. This calculation is commonly used in finance, economics, and other fields to understand changes in data over time or between different categories.
Let’s say we want to find out what percentage of our total expenses last month was spent on groceries. We know that our total expenses were $2000 and our grocery bill was $500. The first step is to express these numbers as fractions.
Total Expenses = $2000 = 100/100
Grocery Bill = $500 = x/100
We use “x” as the unknown variable representing the amount that we want to find out – the percentage spent on groceries.
Next, we set up a proportion equation where the two fractions are equal:
100/100 = x/100
To solve for “x”, we cross-multiply and get 100x = 50000. Then, we divide both sides by 100 to isolate “x” and find that x= 50000/100= 50.
This means that 50% of our total expenses were spent on groceries last month. To check our work, we can also calculate this using a formula:
Percentage = (Part ÷ Whole) x 100
In this case, the part represents our grocery bill ($500) and the whole represents our total expenses ($2000). So,
Percentage spent on groceries= ($500 ÷ $2000) x 100= (0.25 ) x 100=25%
Our answer matches with the previous calculation! Now let’s look at another scenario where we want to find out what percentage of students voted for different candidates in an election:
Candidate A received votes from 45 students out of a possible total of 60 students.
Candidate B received votes from only from only10 students out of the same total possible voters.
To calculate each candidate’s percentage, we first express the votes as fractions:
Candidate A = 45/60
Candidate B = 10/60
We can simplify these fractions to get:
Candidate A = 3/4
Candidate B = 1/6
Then, we set up a proportion equation where the two fractions are equal and cross-multiply:
3/4 = x/100
The fraction “x” represents the percentage of students who voted for Candidate A. Solving this equation gives us x= (3*100)/4= 75%. This means that Candidate A received 75% of the votes.
Similarly, for Candidate B,
1/6 = y /100
Solving this gives us y= (1*100)/6=16.67%, which means that Candidate B received approximately 16.67% of the votes.
Calculating percentages may seem intimidating at first, but with practice and by following a few simple steps, you will have no trouble finding percentages in
