Question

Evan spent 20 hours doing homework last week. This week he spent 25 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

Evan spent 25 percent more time. Not 125 percent.

I used a proportion to answer this questions.

20=25

100 ?

You cross multiply: 25 times 100 is 2,500. 2,500 divided by 20 is 125.

So Evan is incorrect

If this is wrong I'm sorry

Answer 2

25/20 =1.25 -1 =.25 x 100 =25% more time spent on his HW.
