Question

A professor said 4/5 of his students passed the final examination. If 60 students took the exam, how many passed?

Answer 1

48 students.

4/5 x/60

5•x=5x
60•4= 240
5x/5=x
240/5=48

Answer 2

Hey there!

We have that 4/5, or 80% of the 60 students passed the exam.

Thus, we have:

0.8(60)=48

48 students passed the exam.

Let me know if this helps :)
