Have you ever eaten sour lemon candies? Have you ever counted them?

At the candy store, .125 of the jar of sour lemon candies were purchased by a customer. Jake was working at the time and was amazed that only a small portion of the lemon candies went home with the customer.

Can you write this decimal as a percent?

What percent of the jar was purchased?

**To figure this out, you will need to know how to write decimals as percents. This Concept will teach you what you need to know.**

### Guidance

Just like we can write percents as decimals, we can also write decimals as percents. You saw a situation like this in the last Concept. In a way, you reverse the steps from turning a percent to a decimal to turn a decimal to a percent.

**Follow these steps to write a percent as a decimal**

**Step 1: Move the decimal point two places to the right. Add zeros to the right of the decimal point as placeholders, if necessary.**

**Step 2: Write a % symbol after the resulting number**

*Take a few minutes to write these notes in your notebook. Then continue.*

Let’s apply these steps.

Write .78 as a percent.

**This decimal is written in hundredths, so all we have to do is move the decimal two places to the right and add a percent sign.**

Write .6 as a percent.

**This decimal is written in tenths. When we move the decimal two places to the right, we will need to add a zero place holder.**

Write .345 as a percent.

**This decimal is written in thousandths. We only need to move the decimal two places to the right to make it a percent, so we will move it two places and add a percent sign.**

*Notice that sometimes we can have a decimal in a percent. It means that we have 34 and one-half percent in this case. Don’t let that throw you off-not all percents are whole percents!*

**Write each decimal as a percent.**

#### Example A

**Solution: 45%**

#### Example B

**Solution: 250%**

#### Example C

**Solution: 87.5%**

Here is the original problem once again.

At the candy store, .125 of the jar of sour lemon candies were purchased by a customer. Jake was working at the time and was amazed that only a small portion of the lemon candies went home with the customer.

Can you write this decimal as a percent?

What percent of the jar was purchased?

To write this as a percent, we know that we need to move the decimal point two places, representing hundredths, and add a percent sign.

**The customer purchased 12.5% of the lemon candies.**

### Guided Practice

Here is one for you to try on your own.

Write 3.5 as a percent.

**Answer**

This decimal is written with a whole number and five tenths. We still move the decimal to the right two places. Notice that because we have a whole number that the percent will be greater than 100.

**This is our answer.**
