Answer :
//Work backwards from what your original equation would be.
54 = 75/100 * x
54 * 100 = 75 * x
(54 * 100) / 75 = x
x = 72
54 = 75/100 * x
54 * 100 = 75 * x
(54 * 100) / 75 = x
x = 72
rule of three
x ---- 100%
54 --- 75%
75x = 100 . 54
75x = 5400
x = 5400/75
x = 72
answer : 72 ...
Good studies!!
