nothing Comparing Ratios 6.RP.3a

Write the equivalent fractions represented by the models nothing -2 Write the equivalent fractions represented by the models HideAns 6/15 = 2/5 2/10 = 3/5 3/15 = 1/5 6/10 = 2/5

Essential Question: How do you write ratios and equivalent ratios? I want to learn about Ratios and Proportions Essential Question: How do you write ratios and equivalent ratios? My Goal For Today :_____________________ write ratios and make equivalent ratios

I can write equivalent ratios in tables.

Guided Practice Anna’s recipe for lemonade calls for 2 cups of lemon juice and 3 cups of water. Bailey’s recipe calls for 3 cups of lemon juice and 5 cups of water. 1. In Anna’s recipe, the ratio of lemon juice to water is:__________________. Complete the table with equivalent ratios. Lemon Juice (c) 2 4 Water (c) 3 9 15

Guided Practice 2. In Bailey’s recipe, the ratio of lemon juice to water is:__________________. Complete the tables with equivalent ratios. 3. In each table, there is a column in which the amount of water is the same. Circle these columns in the tables. Lemon Juice (c) 3 9 12 Water (c) 5 25

Reflect Examine these two columns. Whose recipe makes stronger lemonade? How do you know?

Examples on your own Complete the table.
