Question

A math class has a total of 41 students. The number of females is 9 less than the number of males. How many males and females are in the class?

Answer 1

41 = g + b

g = girls

b = boys

To find g, we need to do b - 9

So, 41 = (b - 9) + b

41 = 2b - 9

Add 9 to both sides

50 = 2b

Divide both sides by 2

25 = b

So, there are 25 boys

25 - 9 = 16

So, there are 16 girls.

16 + 25 = 41

There are 25 boys and 16 girls in the class.
