About this worksheet

What students practice

Students write a fraction with denominator 10 as an equivalent fraction with denominator 100.
Students add a fraction with denominator 10 and a fraction with denominator 100, like 3/10 + 25/100 = 55/100.
Students explain why tenths must be renamed as hundredths before adding.

How to use

Use after students know that 1/10 = 10/100. Show a meter stick: each long section is 1/10 of a meter and each small mark is 1/100 of a meter. Have students rename the tenths before they add.
