Question

Nick's class has 30 students. 2/5 of his class sings in the choir. How many students sing in the choir?

Answer 1

Multiply 2/5 by 30
2/5*30/1=60/5
now simplify
divide both the numerator and the denominator by 5, and that is equal to  12/1, which is just 12.
so 12 students sing in the choir.
