Answer:
80 questions
Explanation:
You can write a proportion to solve this. A proportion is an equation that sets two ratios equal.
The first ratio is 60/x where x is the number of questions. The second ratio is 75/100. This is the percent you got on the test. Cross multiply to sole for x.
![(60)/(x) = (75)/(100)\\ 60*100 = 75(x)\\6000 = 75x\\80 = x](https://img.qammunity.org/2020/formulas/mathematics/high-school/wrvsfb2oqnqoftgftzdfek1id3e1724x30.png)
