here is the easy way...
u are dealing with equivalent fractions. Equivalent fractions can be found by multiplying the numerator and the denominator by the same number.

 3          ?
----   = -----
 8         24

okay....8 x what is 24 ? 8 x 3 is 24....so u multiplied the denominator by 3, now multiply the numerator by 3.....3 x 4 = 12
so ur missing number is 12.
3/8 = 12/24

5/13 = ?/52.....13 x 3 = 52....multiplied denominator by 3, so we multiply numerator by 3 giving us 15.
5/13 = 15/52

7/12 = x/36...another way u can do it is cross multiply
(12)(x) = (7)(36)
12x = 252
x = 252/12
x = 21......so 7/12 = 21/36
