Question

Three students took a math test.

• Liam completed the test in 2/4 hours
• Sarah completed the test in 1/2 of Liam's time
• Emma completed the test in 4/3 of Sarah's time

How long did it take for Sarah to complete the math test?

Answer 1

20 minutes

Explanation:

Liam completed the test in 1/2 of an hour. One half of that, Sarah's time, is 1/4.

Hence, you don't even have to solve for Emma's time, Sarah took twenty minutes to complete the test.

Hope this helps :)
