Step-by-step explanation:

first, we need to find out how many students in the school are boys.

if 60% are boys, the rest 40% must be girls. if that 40 percent of some unknown number is 12, so the equation formed is 40/100 n = 12, where n is the unknown

we now, solve it

4/10 n = 12

2/5 n = 12

n = 12 x 5/2

n = 30

since this equation meant that the amount of girls of the number of students at the school is 12, the variable n means the number of students in the school, and if n = 30, the number of students in the school are 30.
