there are 30 students in mr. Holland music class. If 30% of the students play in the school band, how many students in the class play in the school band?

Answer :

To calculate percentage, we turn the percentage into a decimal.

30% of 30 = 0.3 of 30 = 0.3 x 10

0.3 x 10 = 3

3 students play in the school band.
