Class test · Ratios and proportional relationships
See the idea, then try it A ratio compares two amounts. In a model with 2 blue parts for every 3 red parts, doubling both amounts makes 4 blue parts for every 6 red parts.
A visual model of equivalent ratios Two blue parts and three red parts are doubled to make four blue parts and six red parts. Both rows keep the same ratio. 2 blue : 3 red 4 blue : 6 red Multiply both parts by 2; the relationship stays the same. Try it A recipe uses 2 cups of oats for every 3 cups of fruit. How many cups of each would keep the same ratio if you doubled the recipe?
Check your thinking Use 4 cups of oats and 6 cups of fruit. Both amounts were multiplied by 2.
