50.6
Step-by-step explanation:
This is what I got. I hope it's correct.
Let the unknown number be x
[tex] 79 \% \: of \: x = 40[/tex]
% = /100
[tex] \frac{79}{100} \times x = 40 \\ \frac{79x}{100} = 40[/tex]
Cross Multiply
[tex]79x = 100 \times 40 \\ 79x = 4000[/tex]
Divide both sides of the equation by 79
[tex] \frac{79x}{79} = \frac{4000}{79} [/tex]
Simplify
[tex]x = 50.6329 \\ \\ x = 50.6[/tex]
