Question

115% of what number is 120?

Answer 1

115% of x =120

115/100*x=120

23/20*x=120

23/20=120/x

x=20*120/23

x=104,34

Answer 2

115% is the same as 1.15
some number = x

115% of some number is 120
1.15 of x is 120
1.15 * x = 120

`(1.15*x)/(1.15) = (120)/(1.15)`
x = 104.3478
x ≈ 104.3

Hope this helps! :)
