Hello there.

Question: Ninety percent of a school's students, or 540 students, attended a school assembly. how many students are there at the school?

You could calculate 10% of it first to help.
90%/ 9 = 10%
If 90% is 540, then 10% is 60.
10% x 10 = 100%
60 x 10 = 600 

In short, Your answer is there are 600 students at the school.

Hope This Helps You!
