# Convert Fractions to Decimals & Percents: FREE Puzzles

*Learn strategies to convert fractions to decimals & percents, plus grab a cute set of pizza matching puzzles to practice this math skill!*

Ask my nine-year-old boy what he wants for dinner, and you are always going to get the same answer:

Pizza!

He is a creature of habit so each time pizza enters our home, he wants it with pepperoni.

Knowing his deep love for pizza, I decided to create some pizza puzzles for him. As he focuses on decimals and their relationship with fractions and percents…I knew he could use a little more practice. So this week he will be using these pizza puzzles to **convert fractions to decimals, and then decimals to percents. **

## Pizza Puzzle Set Prep-Work:

These fun pizza puzzles require just a little prep-work, then your kids will be ready to convert fractions to decimals and percents.

- First, print off the puzzles that you would like to use on card stock paper.
- Next, cut on the black lines so that each pizza is divided into three parts: a fraction, decimal, and percent (each representing the same value)
- Make sure your kiddos have a place to work out the problems, like a whiteboard, and you are ready to go!

**Strategies to Convert Fractions to Decimals:**

There are so many different ways to convert fractions to decimals. Here are a few ways you can use to teach this math concept to your children.

**Changing the Denominator to 100:**

One easy way is to change a fraction’s denominator to 100.

Factions like one-half make this strategy easy.

1/2 x 50/50 = 50/100

This means that the decimal fifty hundredths and can be written like 0.50! But it is also important to understand that 50/100 is equivalent to 5/10. Therefore, you can also say five-tenths or 0.5.

**Divide the Fraction to Convert to a Decimal:**

When children learn about fractions they need to understand that fractions are also division problems.

Activities like these word problems can help children see **how division relates to fractions**.

Once this understanding is developed, changing any fraction to a decimal is as simple as division.

When you have a fraction where the denominator does not equally go into 100, this strategy is the way to go.

With 9/13 it is best to divide.

Our kiddos are so used to seeing the bigger number inside the division sign, that they often do the same thing when trying to solve a problem like this.

When teaching this concept, I repeat over and over that the **n**umerator goes **IN**….they both have those prominent “n” sounds.

To solve these pizza puzzles, kids need to **divide out to four digits**.

This way they can **round to the nearest thousandths place** and find the matching pizza piece.

**How to Convert Decimals to Percents:**

Once a fraction is converted to a decimal, it is quite easy to change it to a percent.

All you need to do is **multiply the decimal by 100** and then * add a percent sign*.

Before you simply tell your children how to quickly solve the problem, I highly suggest you do activities that help children visualize why this works.

Most kids will know that when you multiply a number by 100, you are just moving the decimal two places to the right.

Though this is a great rule, and it makes solving the problems easy, children need to **understand why this works and be able to visualize it.**

As an example, we convert 0.556 to a percent like this:

0.556 x 100 = 55.6%

I hope your hungry, pizza-loving students enjoy this fun way to **practice converting fractions to decimals, and decimals to percents.**
