Question

A classroom had 16 computers. If the ratio of computers to ipads was 4 : 5, how many ipads does the classroom have?

Answer 1

20 iPads

4 computers : 5 iPads is the ratio

16 computers means we’re multiplying the ratio x 4. 5x4 = 20

You can also set it up to cross-multiply and divide:

4/5 = 16/x
4x = 80
x = 20
