## What Are Percentages? A Kid-Friendly Definition

Let's start with a definition of percentages you can share with your students!

Identified by the % sign, percentages are a way of expressing a number as a portion of 100. You can also think of percentages as a way of comparing things on a scale from 0 to 100. If something is 50 percent, for example, that means it's halfway between 0 percent (which means none) and 100 percent (which means all).

Picture a pizza. Now imagine it had 100 slices (hey, we can dream!).

If you and your friends ate 10 slices of pizza, you would have eaten 10% of the pizza! If you ate 50 slices, you would have 50% of the pizza left ... and maybe a bellyache.

## How Do You Calculate Percentages?

To calculate a percentage, you need to divide the part (aka the value or quantity you want to find the percentage of) by the whole (aka the total value or quantity) and then multiply the result by 100.

To make things simpler for young math students, there's a formula for calculating a percentage:

Let's say you want to find the percentage of 50 that 20 represents. Using the formula, you would divide 20 by 50 and then multiply the result by 100, like this:

- percentage = (20 / 50) x 100
- percentage = 0.4 x 100
- percentage = 40%

## How Do You Convert a Decimal Into a Percent?

Converting a decimal into a percent involves multiplying the decimal by 100 and adding a percent sign (%).

For example, let's say you have a decimal of .75.

- 0.75 x 100 = 75%
- So, the decimal 0.75 is equivalent to 75%.

A visual aid like a pie chart or a fraction bar can help illustrate this concept. For example, if you have a fraction bar that represents 1 whole, with 4 out of 5 parts shaded, that would be equivalent to a decimal of 0.8.

To convert this decimal into a percent, you would multiply it by 100 and add a percent sign, which would give you 80%.

## How Do You Convert a Percent Into a Decimal?

What if you already have a percent? It's simple for students to perform the inverse operation! To convert the percent into a decimal, they need to divide it by 100, rather than using multiplication.

Let's use an example again. Let's say you want to turn 50% into its decimal form.

- 50% ÷ 100 = 0.5
- So, the percent 50% is equivalent to the decimal 0.5.

Students may also realize that you just need to move the decimal point to the left two places (because of the two zeroes in 100) to create the decimal.

## How to Turn a Fraction Into a Percent

To turn a fraction into a percent, students need to first convert the fraction into a decimal, then multiply the decimal by 100 and add a percent sign.

Let's work through an example. Suppose you have a fraction of 2/5, and you want to convert it into a percent.

- Convert the fraction into a decimal by dividing the numerator (top number) by the denominator (bottom number):
- 2 ÷ 5 = 0.4
- The fraction 2/5 is equivalent to the decimal 0.4.

- Multiply the decimal by 100 and add a percent sign:
- 0.4 x 100 = 40%
- The fraction 2/5 is equivalent to the percent 40%.

## How to Find the Whole When Given a Part and the Percent?

One of the math skills students will learn as part of their percent instruction is finding the whole when they have been given the part and the percent.

This can be done using the formula Whole = (Part ÷ Percent) × 100.

Let's break it down, step by step:

- Let's say 8 students, which is 25% of the class, submitted a project early. The total number number of students (the whole) is the unknown value.
- We can identify the parts of this problem and determine that 8 is the part and the percentage is 25%
- Plug in the values you know into the formula:
- Whole = (Part ÷ Percent) × 100
- Whole = (8 ÷ 25) × 100
- Whole = 32

The result you get is the whole. In this example, the total number is students is 32.

## How to Find the Part When Given the Whole and the Percent

Now let's flip things around. Instead of giving your students the part and the percent, what happens if you give them the whole and the percent? Now they have to find just the part.

To do this, you'll need to multiply the whole by the percent as a fraction (percent/100).

Let's say you have a pizza that has been cut into eight equal slices (this is usually how it's done!). That's the whole pizza. Now, let's say you want to know how many slices of pizza you will get if you eat 25% of the pizza.

Percent means "per hundred," so 25% is the same as 25 per hundred or 25/100.

To find out how many slices of pizza 25% is, you can multiply the whole pizza (which is eight slices) by 25/100. Don't forget to use PEMDAS!

- 8 x (25/100) = 2
- So, if you want to eat 25% of the pizza, you would eat 2 slices.

## How to Find the Percent When Given the Whole and the Part

But what if you have the whole and the part? How do you now find the percent?

To find the percent, you'll need to divide the part by the whole to get the fraction or decimal that represents the part of the whole. Then convert that decimal to a percentage.

Yes, we're going to talk about pizza again!

Let's say you have a pizza that's made up of 8 slices. You know that your whole is 8 slices.

Now let's say that you have eaten 6 slices. What percentage of the pizza have you eaten? Let's plug it into the formula:

- 6 ÷ 8 = 0.75 × 100 = 75%
- Using the process above for converting a decimal into a percent, this means that 6 slices represent 0.75 or 75% of the total number of pizza slices.
