in a middle school glee club, 2/5 of the singers are sopranos, 1/3 are altos, and the rest are tenors. If there are 90 students in the glee club how many of them are tenors?

To find the fraction of the glee club that are tenors, we first need to add
(2)/(5) and
(1)/(3) before subtracting the sum from 1.


(2)/(5)+ (1)/(3)= (6+5)/(15) = (11)/(15)

1- (11)/(15) = (4)/(15)

Thus, we know that
(4)/(15) of the middle school glee club students are tenors. We simply get the actual number of tenors by multiplying this fraction to the total number of students in the glee club.


(4)/(15) *90=24

ANSWER: 24 students in the glee club are tenors.
