Question

in a class 60% of the students are girls there are are 24 girls in the class how many boys are in the class

Answer 1

Girls=60% of x

so girls 60/100

so left 40%which are boys and girls are given which is 24

students are girls and given they are 24

So total students X= total girls+ total boys

X = (60/100)*X+24

X - (60/100)*X = 24

(40/100)*X = 24

X = (24*100)/40.

X = 60

so there are 60 boys

Answer 2

16

Explanation:

Let s represent all students in the class

.60(s) = 24 This equation means that 60% of students are the 24 girls in class.

Solve for s: s = 24/.60 = 40 There are 40 students in the class

Now to find how many boys are in the class, subtract 24 from 40

40 - 24 = 16

There are 16 boys in the class
