Question

Suzane can work 10 math problems in 15 minutes. How many can she work in an hour and a half? help

Answer 1

60 math problems

Explanation:

15 minutes fits into an hour and a half (90 minutes) 6 times

So we simply multiply what she can do in 15 minutes (10 math problems) by 6

10 x 6 = 60

So Suzanne can do 60 math problems in an hour and a half
