Answer:
1.71 cups
Explanation:
A recipe calls for 12 cups of blueberries to make 7 jars of blueberry jam.
We solve this problem by dividing 12 by 7 to get how many cups of blueberries use to make 1 jar of blueberry jam.
therefore,
= 1.71 cups of blueberries.
In each jar 1.71 cups of blueberries would use.
