Devonte has a meter stick. His teacher tells him that 1 meter equals 0.001 kilometers. He recognizes the decimal, but he isn't sure how to write it in words. What is 0.001 written in words?

In this concept, you will learn how to write decimals in words.

### Reading a Decimal in Words

You read a decimal by using the words that show the place value of the last digit of the decimal.

To help read a decimal, you can put it into a place value chart.

Let's use 0.45 as an example.

Hundred Tens Ones Tenths Hundredths Thousandths

Ten

Thousandths

. 4 5

You read this decimal by using the place value of the last digit to the right of the decimal point. This number is read as forty-five hundredths because the last digit is in the hundredths place.

You can also use place value to write the number.

First, write the number as you normally would.

Forty-five

Then, add the place value of the last digit to the right of the decimal point.

Forty-five hundredths
