Question

There are 45 male teachers and 75 female teachersin a school. Find the percentage of male teachers, female teachers in the school.​

Answer 1

37.5% are male

62.5% are female

Explanation:

in total 120 teachers (45 male+75 female)

therefore:

for male

120 - 100%

45 - x% (we need to find x)

by using the butterfly method (or cross multiply) we get:

120x=100*45

x=4500/120=37.5% (male teachers)

we do the same for female but instead of using 45 we will use 75(the quantity of female theachers in school)

120x=100*75

x=7500/120=62.5%
