Jonah baked a berry pie. The recipe called for 9 ounces of blackberries, 10 ounces of raspberries, and 12 ounces of strawberries. In the supermarket, he only found 12-ounce containers of berries. He bought 1 container of each kind of berry. After he baked the pie, how many ounces of berries did Jonah have left?

5

Step-by-step explanation:

He bought 1, 12 ounce container for each of the set of berries. The blackberries needed 9 but he had 12 so you take the 9 away from the 12 and you are left with 3 you do the same with the raspberries and you are left with 2 then the strawberries are already at 12 ounces so you add up the 3 and the 2 and you get 5.

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
