There are b boys an g girls in the class

b / g = 8 / 17

Multiply both sides by g

b = 8 g / 17

b + g = 375

8 g / 17 + g = 375

8 g / 17 + 17 g / 17 = 375

25 g / 17 = 375 Multiply both sides by 17

25 g = 375 * 17

25 g = 6375 Divide both sides by 25

g = 6375 / 25

g = 255

b = 375 - 255

b = 120
