Question

40 hours is 79% of what?​

Answer 1

50.6

Explanation:

This is what I got. I hope it's correct.

Let the unknown number be x

`79 \% \: of \: x = 40`

% = /100

`(79)/(100) * x = 40 \\ (79x)/(100) = 40`

Cross Multiply

`79x = 100 * 40 \\ 79x = 4000`

Divide both sides of the equation by 79

`(79x)/(79) = (4000)/(79)`

Simplify

`x = 50.6329 \\ \\ x = 50.6`
