Question

Darren teaches a class of 25 students. He assigns homework 3 times a week, and each assignment consists of 12 problems. How many problems must Darren correct each week? 225 problems

Answer 1

I think its 900
 because I did 12x3 for each day and then that gave me 36 then I did 36x25 cause there's 25 kids which gave me 900

Answer 2

12 x 3 = 36

So each student has 36 problems

25 x 36 = 900

So Darren must correct 900 problems each week.



Alternatively, you can just do this if it's easier for you:

25 x 12 = 300
300 x 3 = 900
