What is Ratio?
Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.
The ratio of boys to girls in a school is 12:25
Let, No. of boys in the school = 12x
No. of girls in the school = 25x
Total students in the school = 12x+25x = 39x
Given, there are 120 boys
So, 12x = 120
x = 10
No. of girls in the school = 25x = 25(10)
No. of girls in the school = 250
Total students in the school = 39x = 39(10)
Total students in the school = 390
Hence, 250 girls are in the school and 390 total students in the school.
