Math


In math today we learned about rates. Rates are a comparrasin of 2 numbers. We also learned about Unit Rates. When you have a unit rate the second term always is the number one. Say if you have 5hours as the second term. To make it into a unit rate you have to divide the number by 5 and you get 1hour for the second term. Also the line / means per.


Example: $52.00/5hours = $10.40/1hour.
