You can put this solution on YOUR website! There are 357 seniors in Harris High School. The ratio of boys to girls is 7:10. How many boys are in the senior class?
--------------------
7:10 is the same as 7x:10x where 7x represents the number of boys.
--------------------
Equation:
7x + 10x = 357
17x = 357
x = 21
Then 7x = 147 (# of boys)
