Question

Jessie finishes 2/5

of the problems on her homework before dinner. She finishes

another 3/10

of the problems on her homework after dinner. What fraction of the

problems on her homework does Jessie still have left to do?

Answer 1

Answer: Jessie still has 3/10 left.

Explanation:

Convert 2/5 into tenths by multiplying by 2.

2/5 x 2 = 4/10

3/10 + 4/10 = 7/10

The entirety of her homework is 10/10 so do

10/10 - 7/10 = 3/10

She has 3/10 left.
