Question

What is the unit rate​

Answer 1

Answer:

Step-by-step explanation:

A unit rate is a ratio that is used to compare different kinds of quantities. It describes how many units of the first type of quantity corresponds to one unit of the second type of quantity. Some common unit rates are miles/kilometers per hour, cost per item etc

Alternatively, A unit rate is a ratio between two different units with a denominator of one.

When we divide a fraction's numerator by its denominator, the result is a value in decimal form. Examples include 8 / 4 = 2 and 3 / 6 = 0.5. When we write numbers in decimal form, they could always be written as a ratio with one as the denominator. 2 could be written as 2 / 1, and 0.5 could be written as 0.5 / 1. However, that would just be clumsy and in the way, so we usually drop the one. However, it is important to know that it is there, especially with unit rates.

For the above ratios, if we were talking about 8 miles / 4 hours, dividing the two would give us 2 miles / hour. Notice again that we did not write or include the one, but that we did include the unit 'hour.' Miles / hour is familiar, as are unit rates such as revolutions / minute, salary / year, and interest / amount invested. Conversationally, the word 'per' indicates we are using a unit rate.
