Derick studied 13 1/2 hours this week for a spelling bee. Write the number of hours as a decimal.

13.5

Step-by-step explanation:

When you convert fraction numbers to decimal numbers, remember they are written like this:

whole. parts

In 13 1/2, you have 13 wholes and 1/2 parts. The decimal number would look like 13. parts

To find the decimal for 1/2, put into your calculator 1 : 2. The answer will be 0.5 Write "5" for parts. The decimal where 0.5 is will line up with the decimal in the decimal number.

13.5
