Question 328019
Here we have a test with 20 questions. With each question being worth 3 points.

Let's multiply the number of questions by the point value to determine the total number of points possible for the test:

20 * 3 = 60.

So the test is worth 60 points.

The student scored 48 points out of 60 points. Next we determine the percentage the student answered correct:

48 / 60 = .80 

The student scored 80% or .80 on his / her test. Now we take this .80 to determine the actual amount of problems the student got correct.


There were 20 questions, so the student got 80% of the 20 questions correct. We use multiplication as the word "of" denotes multiplication:

.80 of 20 = .80 * 20 = 16 questions answered correctly.

You can check your answer also: 
16 questions answered correctly * 3 points = 48 Yes!!!

Good Luck :-)
