Find Unit Rates Quick Check
A unit rate is a comparison of two different quantities with a denominator of 1. It allows for easier comparison between two different sized quantities. To find a unit rate, divide the quantity being compared by the unit of measure.
Here's an example: If you are trying to compare the cost of 5 apples to the cost of 2 oranges, you would divide the cost of the apples (let's say it's $10) by the number of apples (5), and divide the cost of the oranges (let's say it's $6) by the number of oranges (2). So the unit rates would be $2 per apple and $3 per orange.
To find unit rates, you can follow these steps:
1. Identify the two quantities you want to compare.
2. Determine the unit of measure for each quantity.
3. Divide the quantity being compared by its respective unit of measure.
Here are some quick check questions on finding unit rates:
1. If you drive 150 miles in 3 hours, what is the unit rate of miles per hour?
- Divide 150 miles by 3 hours to get a unit rate of 50 miles per hour.
2. If it takes 2 hours to cook 4 cakes, what is the unit rate of cakes per hour?
- Divide 4 cakes by 2 hours to get a unit rate of 2 cakes per hour.
3. If you can read 60 pages in 4 hours, what is the unit rate of pages per hour?
- Divide 60 pages by 4 hours to get a unit rate of 15 pages per hour.
Remember, unit rates allow for easier comparison between different quantities, especially when using different units of measure.
