Hi please solve the 7th question. Thanks

Answer 1

Answer:

I) 36:65 ii) 65:26 iii) 3:2

Step-by-step explanation:

no of students = 130

ratio of girls to boys =2:3

let the ratio be x

then no of boys=3x and no of girls=2x

total no of students=3x+2x=5x

5x=130

x= 26

I)no of boys to no of students=(3*26):130

=78:130 or 36:65

ii) no of students to no of girls=130:(2*26)

= 130:52

=65:26

iii) no of boys to no of girls=78:52 or 3:2
