School books

At the beginning of the school year, the teacher distributed 480 workbooks and 220 textbooks. How many pupils could have the most in the classroom?

Correct answer:

n =  20

Step-by-step explanation:

10<n<40  480=25⋅3⋅5 220=22⋅5⋅11 GCD(480,220)=22⋅5=20  n=GCD(480,220)=20  s=480/n=480/20=24 u=220/n=220/20=11  n=20=20
