question: find the percentage A is of B
= (B-A)/B x 100 . You must then take the answer and subtract it from 100 to get the correct answer, which would make the formula:
(B-A)/B x 100 = C, 100 - C = percentage A is of B
for example, find what percentage 57 is of 90:
B - A
90-57=33
/B
33/90=0.3666
x 100
0.3666 x 100 = 36.66.
100 - 36.66 = 63.33, which is the percentage that 57 is of 90
