Today, we learned about ratios and unit rates.

Make sure you understand that ratios can be written in three ways:

1. a/b 2. a : b 3. a to b

Don't forget to simplify if you are able to reduce a fraction:

For Example:

* * * $ $ $ $ $ $

The ratio of stars to dollar signs would be:

3 : 6 3 to 6 3/6

Since 3/6 can be reduced to 1/2, we change the ratios to:

1 : 2 1 to 2 1/2
