The number of boys in the group is 15 and there are 35 students. This gives the number of girls as 35 - 15 = 20

The ratio of the number of boys to the number of girls is 15:20 = 3:4.

The required ratio of the number of boys to the number of girls is 3:4.

Well first you have to find the number of girls in the class.

so you  take the number of boys from the total number of class members

35-15= 20 girls 

So the ratio from boys to girls is

15:20 

which can be simplified to 

3:4 if we divide both sides by four

3:4

 

Since, there are 15 boys and overall 35 students, you subtract the amount of boys and there will be 20 girls left. Now its 15/20 or 15 to 20, but simplifying that amount, you will have 3 to 4. And since you ask for the boys, it would be 4:3 in ratio format.

First you should subtract the boys with the overall students getting 20 girls. then it is 15/20 and the ration would be 3:4
