Here is a very simple way:

Ratio of

bulding A: building B = 3:2 = 3x:2x

then 5x = 60

x = 12

3x = 36 ---> building A

2x = 24 ---> building B

Just realized it said "elementary" so I don't know if you know how to work with variables.

Here is another way

Bld A Bld B Total

3 .. 2 .. 5

6 .. 4 .. 10

12 .. 8 .. 20

24 .. 16 .. 40

30 .. 20 .. 50

36 .. 24 .. 60

notice 3/2 = 6/4 = ... = 36/24
