Question

Chloé had 100 math problems to complete over the 3-day weekend. She recorded the number of problems in her math journal. She completed 39/100 of the problems on Friday,5/10 of the problems on Saturday,and another 15 problems on Sunday. Did chloe fill out her math journal correctly ?

Answer 1

Yes, Chloe fill out her math journal correctly.

Explanation:

Total number of math problem = 100

Problems solved on Friday =
`(39)/(100)` × 100 = 39

Problems solved on Saturday =
`(5)/(10)` × 100 = 50

Problems solved on Sunday = 15

Total number of math problem in three days = 39 + 50 + 15 = 104

But the student have only 100 math problems to solve in three days . so he achieved the target. thus Chloe fill out her math journal correctly.
