Question

Carly needed to study for 5/6 of an hour for 9 days. How many hours did she study?

A. 9 5/6 hours
B. 7 1/2 hours
C. 2 1/7 hours
D. 7 hours

Answer 1

B. 7 1/2 hours

Explanation:

5/6 times 9 can be written as 5/6 times 9/1. Then, you just multiply the numerators (the top numbers), and then multiply the denominators (the bottom numbers). 5x9=45, and 6x1=6, so 5/6 times nine is 45/6, or 7 1/2.
