Answer 2

3/4 of his allowance on food....he spends $9 on food...so $9 is 3/4 of his allowance.

(3/4) / 9 = (4/4)/x -- (3/4 to $9 = 4/4 to x)
cross multiply
3/4x = 9(4/4)
3/4x = 9
x = 9/(3/4)
x = 9 * 4/3
x = 36/3
x = 12

check..
3/4 of 12 = 9
3/4 * 12 = 9
36/4 = 9
9 = 9 (correct)

Tom's weekly allowance is $12
