Norma answered correctly 3 out of every 4 questions in the mathematics benchmark.
This means that she answered correctly 3/4 of the mathematics benchmark.
Since the total number of questions is 36, we need to find how much is 3/4 out of 36.
We can find this by multiplying 3/4 by 36:
To solve this operation, multiply 3 times 36 and then divide the result by 4:
3/4 out of 36 is 27, thus, she answered 27 questions correctly.
Answer: 27
