A biology class has a total of

students. The number of females is
9
less than the number of males. How many males and how many females are in the class?

47 (total) - 9 (difference) = 38 (balance) ÷ 2 (male/female)
= 19 (females) + 9 = 28 (males)

Hope this helps!

Females:24
Males:33

You would divide 47 by two to get 23.5, since you cannot have a half of a person, round it up to 24, then add 9 to find the number of males(33). Subtract 33 from 47 to get the number of females(24).
