Question

40 % of the students in a class are boys.

Find the ratio of the number of girls to the number of boys in the lowest form.

If there are 24 boys in the class, what is the number of girls?

Answer 1

Answer:

given that

40% = boy

let boys= y and girls = x

find ratio between x and y

students = y+x

100% = 40% + x

100% - 40% = x

x= 60%

the ratio between y and x 4:6 respectively

if 24boys then what is the no of girls

let.

We know that the ratio of y and x

4 : 6

24/4 = x/6

24×6 = 4x

144 = 4x

144/4 = x

x=36
