In a school, there is a total of 640 children. The ratio of Girls to boys is 7:9. How many boys are there in this school?

The first step to this question would be to add both of the ratio values which would be 16.Then you would divide the amount of children which is 640 by the value 16. You would Get 40. Then multiply 40 by 9 which is 360.
