Answer:
Explanation:
A ratio is a comparison of two quantities, typically written in the form a:b or a/b. For example, a ratio of 2:3 represents a comparison of two quantities where the first quantity is 2 and the second quantity is 3.
The related rate of a ratio is the rate at which the ratio changes over time. For example, if the ratio of the number of apples to the number of oranges in a basket is 2:3, and the number of apples is increasing at a rate of 2 apples per minute, then the related rate of the ratio would be 2:3 per minute.
A unit rate is a special type of rate in which the denominator of the ratio is 1. For example, if the ratio of the number of apples to the number of oranges in a basket is 2:1, then the unit rate is 2 apples per orange. Unit rates are often used to compare quantities that are measured in different units.
