Question

18 is what percent of 60

Answer 1

18 = x% * 60

18 = x/100 * 60

18 = x/10 * 6

Multiply 10 on both sides.

180 = x * 6

6x = 180

Divide 6 on both sides.

x = 180/6

x = 30


18 is 30 percent of 60.

Answer 2

100%/x%=60/18
(100/x)*x=(60/18)*x
100=3.33333333333*x (3.33333333333)
100/3.33333333333=x
30=x
x=30

now we have:
18 is 30% of 60
