Question

There are 80 students in the school band.30% of them are sixth graders, 40% are seventh graders, and the rest are eighth graders.

Answer 1

I am assuming you are asking for the percentage of 8th-graders? 40% of the students are 8th-graders.

Explanation:

30% of 80 = 24

40% of 80 = 32

30% of 80 = 24

Add them up, 24 + 24 + 32 = 80!
