a middle school has 360 students. if 3/10 of the students are in sixth grade and 7/20 are in 7th grade, how many students are in 8th grade

Respuesta :

Hello!

3/10 is equal to 6/20. If we add that with 7/20, we have 13/20. This means 6/20 are 8th grades. We multiply 6/20 by 360 below.

6/20(360)=108

Therefore, there are 108 students in the 8th grade.

I hope this helps!
