Question

What is a rate and what is it used for

Answer 1

A rate is how fast something is happening. Let's say, "What is the rate at which I bike uphill?" That's just asking for the average speed (mph) that I'm biking uphill.

Hope this helps! :)

Answer 2

A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. The first term of the ratio is measured in cents; the second term in ounces. You can write this rate as 69¢/12 ounces or 69¢:12 ounces.
