Question

Jacob had 3/4 of his book report left to do. He completed 3/8 more of the report today. What fraction of the book report does Jacob still need to do?

Answer 1

3/4-3/8 make a common denominator of 8

(3/4)(2/2)-3/8

6/8-3/8

3/8

So he has 3/8 more to do.

Answer 2

3/8 left.

3/4=6/8
6/8-3/8=3/8
