1. Equivalent Ratios and Rates
Objective:
Learn to find Equivalent Ratios and Rates.

2. Equivalent Ratios and Rates
You can find equivalent ratios and rates the same way as you find equivalent fractions- by multiplying or dividing both parts of the ratio or rate by the same number.
For example: 6 cookies
2 people
6 cookies x2 = 12 cookies
2 people x2 = 4 people
6 cookies ÷2 = 3 cookies
2 people ÷ 2 = 1 person
