The numerator is the first number. The denominator is the second number. Sign has to be the same and only one negative to make the fraction negative.
We can rephrase the question as "What percent of 50 is 20?".
"What percent ..." is an unknown. We'll use the variable x to represent this unknown.
The word 'of' in mathematics can mean 'multiply'. Likewise the word 'is' can mean 'equal'.
Now we have the phrase "20 equals to x times 50".
Or in an equation: 20 = x * 50
Solve for x.
20 = x * 50

= x <-- Divide both sides by 50
Simplify the fraction.

Convert the fraction into a decimal.

= 0.4
Convert the decimal into a percent.
0.4 = 40%
So, 40% is the answer.
