Question

George is supposed to practice piano for 3/4 of an hour every day. Today, he still needs to practice 1/3 of an hour in order to accomplish his goal. What fraction of an hour has he been practicing today?

A) 13/12
B) 2/3
C) 5/12
D) 1/4

Answer 1

C

Explanation:

All you need to do for this one is put it on a calculator 3/4-1/3

If you need to explain just multiply both the top and the bottom by the other's denominators. ex:9/12 is 3/4 but times 3 for both.

9/12-4/12=5/12
