Question

Pierce has 8 minutes to complete 10 math problems. How many minutes does he have to spend on each problem? Answers:2/10 minute, 8/10 minute, 10/8 minute, or 1 2/8 minute

Answer 1

8 minutes for 10 problems

We want to find the unit rate.
Basically, how long does it take to do just 1 problem?

Divide each number by 10.

8/10 minute for 1 problem

This could simplify to 4/5 because both the top and bottom are divisible by 2, but since 8/10 is one of the answers, pick that.
