Write your own complex fraction that simplifies to ¼

POD

Day 2

If Cole ran 12 miles on Sunday, how many feet did he run?

POD

Day 3

Math Experiment! Let’s put it into practice.

1-3 Convert Unit Rates

Each of these relationships in the tables can be written as a unit ratio.

12 inches

1 foot

16 ounces

1 pound

100 centimeters

1 meter

You can convert one rate to an equivalent rate by multiplying by a unit ratio or its reciprocal.

You must include units in your computation.

The process of including units of measure as factors when you compute is called dimensional analysis.
