Pine Hill Middle School has 300 students. In
Zoey's class, two out of five students belong to
a club. Use this ratio to predict how many
students in the school belong to a club.

Answers

120



Step by step explanation

There are 120 students in the school Pine Hill Middle School who belong to a club.

What is a ratio?

A ratio describes a comparison between two or more quantities in simplest form.

Given that Pine Hill Middle School has 300 students.

Also given two out of five students belong to a club.

∴ We can conclude that (2/5)th of the total students belong to the club which is numerically,

= (2/5)×300.

= 120 students.

We can also solve this by ratios if in a total of 5 students 2 students belong to a club that means 3 students doesn't belong to the club and their ratio is 2:3.

∴ The no. of students belonging to the club is 2/(2+3)×300.

= (2/5)×300.

= 120 students belong to the club.
