Introduction to Percentages

In this intro to percentages lesson, you'll get a chance to fully understand them before calculating and converting them.

Writing percentages

As you saw in the slideshow, every percentage has two parts: a number and the percent sign (%). When you write a percentage, you'll write the number first, then the percent sign. Let's try it! How would you write this percentage?

nine percent

First, we'll write the number, nine, and then the percent sign (%). So our percentage will look like this:

Try writing the correct percentage in the box.

Reading percentages

When you read a percentage out loud, you'll need to read two parts: the number and the percent sign (%). Let's look at an example:


25% is twenty five out of one hundred. We'd read 25% like this:

twenty-five percent

Sometimes percentages might have a decimal. For example:


Here, 7.5% means we have seven-and-a-half out of one hundred. We'd read it like this:

seven point five percent


seven and a half percent

You can read any percentage with a decimal point like this. How about 10.25%? That's ten and one quarter out of one hundred, so we'd read it as ten point two five percent, or ten and a quarter percent.

Try This!

Try reading each of the percentages below aloud.
