# Write each fraction as a decimal

If you think about a pizza that is cut into 4 slices, the 4 represents how many equal parts into which the whole pizza is divided. Here's why the method we showed you works.

But we've expressed this amount in three ways: as a fraction, as a percent, and as a decimal. And then we subtract again. Let's try another example.

### Write each fraction as a decimal

Convert these fractions into percents. So we can divide both parts of the fraction by It doesn't go into it eight times because that's Instead, we'll keep the decimal point and add a percent sign at the end of the number. Let's look at another example. Now we'll move the decimal point two spaces to the left. For example, we could describe the same car as tiny or little or small. Such operations may seem intimidating, especially for those who've been out of school for a while. And I'll do it down here just so I have some more real estate to work with. Let's convert a decimal into a percent. We're going to convert 0. So 8 goes into-- it doesn't go into 7 at all, but it does go into These are all different ways of writing the same thing. We have nothing left over.

We'll also change the decimal point into a percent sign. You have to divide the percent by to get a decimal, but there's a quick way to do that. Be sure to reduce each fraction to its simplest form!

## Decimal to percent

In Introduction to Percents , you learned that all percents are out of And I'll do it down here just so I have some more real estate to work with. Converting a percent into a fraction When you're converting a percent into a fraction, it helps to remember that percents are always out of Photo Credits. We'll divide the numerator of the fraction first. First we'll divide the numerator. So 8 goes into-- it doesn't go into 7 at all, but it does go into These are all different ways of writing the same thing. This way, you can get the same answer with just one easy step.

You know that all percents are out ofso you can skip making the percent into a fraction. Calculate these decimals as percents. Because you can get the answer without them. So 8 goes into 70 eight times.

Let's look at another example. The denominator is always the number on the bottom of a fraction and represents the number of parts into which one "whole" is equally divided. We want to get to the point that we have no remainders. Fractions, decimals, and percents are like the words tiny, little, and small. We'll divide the numerator of the fraction first. Click through the slideshow to see how to convert a decimal into a percent. But it's important if you're going to use the fraction in a math problem. We can't just leave an open space with nothing in it. Click through the slideshow to learn how to convert a percent into a fraction. You know that all percents are out of , so you can skip making the percent into a fraction. Such operations may seem intimidating, especially for those who've been out of school for a while. Click through the slideshow to learn how to convert a fraction into a percent. Now we'll move the decimal point two spaces to the left. Converting a percent into a decimal Converting a percent into a decimal is surprisingly easy.
