Final answer:

Molly got a 65% on the math quiz, and there were 20 questions. To find out how many questions she got right, we can set up a proportion and solve for x. The number of questions she got right is 13.

Step-by-step explanation:

To find out how many questions Molly got right, we can first calculate the percentage of questions she got right. Molly got a 65% on the quiz, which means she answered 65% of the questions correctly. To find out how many questions that corresponds to, we can set up a proportion. Let x represent the number of questions Molly got right:



(x / 20) = 65 / 100



Cross-multiplying, we get:



100x = 65 * 20



Simplifying, we get:



100x = 1,300



Dividing both sides by 100, we get:



x = 13



Therefore, Molly got 13 questions right.
