- A rate is a ratio of two different units.
- A unit rate is a ratio of two units, where the rate or denominator of the second unit is 1.
- A unit rate means the price or quantity of one item of something.
- Finding the unit rate of anything is finding the rate or quantity for one where the rate for more than one is given.
Example 1: Find the unit rate: 92 miles in 2 hours.
Solution: To find miles/hour, write the fraction with the given numbers in such a way that the fraction can be reduced and has 1 as a denominator.
= 46 miles/hour
Example 2: Find the unit price: $12 for 6 burgers
Solution: To find the price of 1 burger, write the fraction with the given numbers in such a way that the fraction can be reduced and has 1 as a denominator.
$2 for 1 burger or $2/burger.
- Finding the unit price is the same as finding the unit rate. In unit rate, the rate of 1 item is determined, and in unit price, the price of 1 item is determined.
- While finding the unit rate or unit price, the denominator of the ratio should always be reduced to 1.
