Question

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.

Answer 1

23 with a remainder of 7. :)

Answer 2

We know that when 45 is divided into 1042 it doesn't come out as even.

So, we have to find a number when divided into 1042 it comes out even.

We know that each exhibit will contain x amount of pictures.

45x = 1042

Divide both sides by 45

x ≈ 23.15

But x have to be a whole number, so keep only the 23 part.

So, 23 pictures in each exhibit 23*45 = 1035

Not quite as 1042

Subtract 1035 from 1042.

1042 - 1035 = 7

Then subtract 7 from 45

45 - 7 = 38

The answer is 38

Hope this helps!
