Question

40 hours is 79% of what?​

Answer 1

50.6

Step-by-step explanation:

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

Let the unknown number be x

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

% = /100

$\frac{79}{100} \times x = 40 \\ \frac{79x}{100} = 40$

Cross Multiply

$79x = 100 \times 40 \\ 79x = 4000$

Divide both sides of the equation by 79

$\frac{79x}{79} = \frac{4000}{79}$

Simplify

$x = 50.6329 \\ \\ x = 50.6$
