Question

48 over 120 = x over 100 cross multiply to get answer of x

Answer 1

`(48)/(120)=(x)/(100) \\ 120x=48 * 100 \\ x=(48 * 100)/(120) \\ x=(48 * 100)/(12 * 10) \\ x=4 * 10 \\ x=40`

Answer 2

`(48)/(120)=(x)/(100)\ \ \ \ \ |(48)/(120)=(48:6)/(120:6)=(8)/(40)=(8:4)/(20:4)=(2)/(5)\\\\(2)/(5)=(x)/(100)\ \ \ \ |cross\ multiply\\\\5(x)=2(100)\\\\5x=200\ \ \ \ |divide\ both\ sdies\ by\ 5\\\\\boxed{x=40}`
