Question

A total of 60 students in Brook's school are taking a Spanish class this year. This is 25% more than the number of students who took a Spanish class last year. How many students took a Spanish class last year?

Answer 1

The answer would be 15. 

An easy way to solve this would be, if you now that 25% is equal to 1/4, then what is 1/4 of 60? It would be 15. Hope this helps! :)
