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
![\frac{20}{50}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B50%7D)
= x <-- Divide both sides by 50
Simplify the fraction.
![\frac{20}{50} = \frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B50%7D%20%3D%20%5Cfrac%7B2%7D%7B5%7D)
Convert the fraction into a decimal.
![\frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D)
= 0.4
Convert the decimal into a percent.
0.4 = 40%
So, 40% is the answer.

Answer:
24 = questions on test
Step-by-step explanation:
Questions answered correctly = questions on test * percent answered correctly
We know that she answered 18 correctly and that 75% were answered correctly
Substitute this information into the equation
18 = questions on test *.75
Divide by .75 on each side
18/.75 = questions on test *.75/.75
24 = questions on test
