Question

how do I find out the answer to 50 is 40% of what number?

Answer 1

50 is 40% of 125

Given:
value = 50
percentage = 40%

This problem involves part and whole. 50 is the part and it is 40% of a whole.

To get the whole, we need to divide the part by its corresponding percentage to the whole..

50 / 40% = 125  *the whole

To check:
125 * 40% = 50
50/125 = 0.40 * 100% = 40%

Answer 2

50 is 40% of 125

Convert the percentage into a decimal:
$\frac{40}{100} = 0.4$

Divide 50 over the decimal:
$\frac{50}{0.4} = 125$
