What is rate and unit rate? and how do you convert a fraction to a decimal?

To convert a fraction to a decimal, you simply divide the numerator by the denominator. 

rate: a ratio that compares two quantities having different units of measure
unit rate: a unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity. examples: miles (or kilometers) per hour, cost per item, earnings per week, etc.

hope this helps!!

1.) A rate is when you compare 2 different measurements, for example:
60 miles per 3 hours

A unit rate is when you compare only one, for example:
30 miles per hour

You can convert a rate into a unit rate by dividing so you can simplify it.

2.) You can convert a fraction into a decimal by dividing the numerator by the denominator.
