Q. Friday night's hockey game was attended by 180 students. This is about 60 % of the school's population. What is the total population of the school?

The total population of the school is 300 students.

Step-by-step explanation:

Considering, we are working with percentage we can use the equation:

y = %x.

To fill in the equation you can use what you already know, 60% = 180

180 = 0.60x

To solve this, you can then divide both sides of the equation by 0.60. This will then give you your answer, 300 = x.

For checking, you can do 180 = 0.60 (300) which will result in 180 = 180.
