Question

Markus spent 12 hours doing his homework last week. This week he spent 15 hours doing homework. He says that he spent 125% more time doing homework this week. Is he correct? Show your work to justify your decision.

Answer 1

He is correct

Explanation:

12=100%

15 is 3 more than 12

12 divided by 3 is 4

100 divided by 4 is 25

100 + 25 = 125
