If 40% of the students are girls then that means 60% of the students are boys.
First, turn 60% into a decimal.
60% = 0.6
Second, divide by the number of boys.
36 / 0.6 = 60 total students
Third, turn 40% into a decimal.
40% = 0.4
Fourth, multiply by the total number of students.
60 * 0.4 = 24 girls
Best of Luck!

Answer:
Step-by-step explanation:
This is a straight forward division problem.
12/(5/8).
The rule for division of fractions is: invert the denominator and multiply.
For this problem: 12/(5/8) = 12 * 8/5 = 96/5.
6x - 12 = 2x + 36
4x = 48
x = 12
4y = 6y - 42
-2y = -42
y = 21
