Question

I got 60 questions correct on my science test if I received a score of 75% how many questions were on the test

Answer 1

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.

$\frac{60}{x} = \frac{75}{100}\\ 60*100 = 75(x)\\6000 = 75x\\80 = x$
