Rates and unit rates

compares two quantities, with or without units.

You can write a ratio in 3 different forms: fraction, colon, the word "to"

You can use a ratio to compare information in three different settings: a part-to-part comparison, a part-to-whole comparison, or a whole-to-part comparison

A rate is a ratio in which two quantities are measured in different units.

For example 12 golf balls for $6 can be written as 12:6. This RATE compares golf balls to their price.

Both a ratio and a rate can be stated i the form of a fraction

can sometimes be expressed as whole numbers because the denominator is assumed to be one

example

A rate with a denominator of 1.

When finding the unit rate, simplify the ratio.

You could also divide.

Basically think... "How much is just 1?"
