Question

1 25% of what number is 13?

Answer 1

Step-by-step explanation:

Let 25% of x be 13

$\therefore \: \frac{25}{100} \times x = 13 \\ \\ \therefore \: \frac{1}{4} \times x = 13 \\ \\ \therefore \: x = 13 \times 4 \\ \\ \therefore \: x = 52$

Hence, 25% of 52 is 13.

Answer 2

25% is 25/100=1/4. If 1/4 of x is 13, then 13x4 would equal x. X=52
