To find the fraction of the glee club that are tenors, we first need to add [tex] \frac{2}{5} [/tex] and [tex]\frac{1}{3}[/tex] before subtracting the sum from 1.
[tex] \frac{2}{5}+ \frac{1}{3}= \frac{6+5}{15} = \frac{11}{15} [/tex]
[tex]1- \frac{11}{15} = \frac{4}{15} [/tex]
Thus, we know that [tex]\frac{4}{15}[/tex] 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.
[tex] \frac{4}{15} *90=24[/tex]
ANSWER: 24 students in the glee club are tenors.
