Reiny,
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

Reiny,
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
