Answer:
80 questions
Step-by-step 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.
[tex]\frac{60}{x} = \frac{75}{100}\\ 60*100 = 75(x)\\6000 = 75x\\80 = x[/tex]
