On a test, Abbey had 75% of the problems right. If she had 48 problems correct, how many questions were on the test?

.75x = 48

x = 48/.75
= ...

To find out how many questions were on the test, we can set up a proportion. Let's call the total number of questions on the test "x".

Since Abbey had 75% of the problems right, this means she got 75% of x questions correct. We can express this as 0.75x.

And we know that Abbey had 48 problems correct, so we can set up the following equation:

0.75x = 48

To solve for x, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 0.75:

x = 48 / 0.75

Calculating this division, we find:

x = 64

Therefore, there were 64 questions on the test.
