Example 1: Use a table to find three equivalent ratios of. Strategy: Create a table and multiply or divide both numbers in the ratio by the same number Original Ratio The ratios and are all equivalent.

Example 2: Use a table to find three equivalent ratios of 40:16. Strategy: Create a table and multiply or divide both numbers in the ratio by the same number Original Ratio 40 ÷ 2 The ratios 40:16, 20:8, 10:4 and 80:32 are all equivalent. 40 ÷ 440 x 2 16÷ 216÷ 416 x 2 Using Tables to Find Equivalent Ratios

Using Ratio Tables to Make Predictions Example 3: A group of 10 friends are in line to see a movie. The table shows how much different groups will pay in all. Predict how much the group of 10 will pay. Number in Group Amount Paid ($) < 10 < 12; therefore, the group will pay between $30 and $60. More specifically, we can work with the group of 5 to find an answer to our question. 5 2 = 10 people 25 2 = $50 Therefore, a group of 10 friends will pay $
