Question

45 is what percent of 54?

Answer 1

54/x=100/45
(54/x)*x=(100/45)*x       - we multiply both sides of the equation by x
54=2.22222222222*x       - we divide both sides of the equation by (2.22222222222) to get x
54/2.22222222222=x 
24.3=x 
x=24.3

Answer 2

for getting percentile you have to divide the smaller no from larger no and multiply it by 100
.
. so (45÷54)×100
= .83×100
=83%
