Hi

Can any of you explain how you do this problem?

An Art museum has 1,042 pictures to split equally into 45 different exhibits.
How many more pictures does the museum need to make sure each exhibit has the same amount?

The museum needs _______________ more pictures

I would look for the multiple of 45 that is closest to 1,042. 23 is too few - 23 x 45 = 1,035. So, to me, I would say that each exhibit would need 24 pieces. 24 x 45 = 1,080. They would need 38 more pictures. (1,080 - 1,042 = 38)

I come up with 38 more pictures needed.

How many 45s in 1042? 23
24 X 45 = 1,080

1,080 - 1,042 = 38

1042 divided by 45 is 23 r7 or 23 and 7/45

If you have 7 out of another set of 45 you need 38 more for the complete set (45/45)
