Question

In Mr. Martin’s class, there are 16 students who are 12-years old and 8 students who are 13-years old. What is the unit rate of 12-year olds to 13-year olds?

Answer 1

To find the unit rate of 12-year-olds to 13-year-olds in Mr. Martin’s class, divide the number of 12-year olds (16) by the number of 13-year olds (8), resulting in a unit rate of 2:1.

Step-by-step explanation:

The question asks for the unit rate of 12-year olds to 13-year olds in Mr. Martin’s class. To find the unit rate, we divide the number of 12-year olds by the number of 13-year olds. Here, there are 16 students who are 12-years old and 8 students who are 13-years old. So, the unit rate is calculated as:

Unit rate = Number of 12-year olds / Number of 13-year olds

Unit rate = 16 / 8 = 2

Thus, the unit rate of 12-year-olds to 13-year-olds in the class is 2:1, meaning there are two 12-year olds for every one 13-year old.
