of the students are boys, and the number of girls is 100. Find the number of boys

​

Answer 1

Answer:

80 members

Step-by-step explanation:

as 1/5×4=4/5 then 100/5= 20 so 20 ×4= 80

Answer 2

Answer:

fraction of students (total)=5/5

fraction of boys=4/5

fraction of girls=5/5-4/5

=(5-4)/5

=1/5

number of girls=100

let, the fraction of girls is 4y/5

A/q,1y/5=100

=>y=100x5/1

=>y=500

=>total students=500

number of boys=500x4/5

=100x4

=400
