You have 23 1/2 pounds of blueberries to store in freezer bags. Each bag holds 3 3/4 pounds of blueberries. What is the minimum
monitta

Answer:

The minimum number of freezer bags needed to store all the blueberries is 7

Step-by-step explanation:

we know that

To find out the number of freezer bags needed , divide the total pounds of blueberries by 3 3/4, but first convert mixed number to an improper fraction

23\frac{1}{2}\ lb=\frac{23*2+1}{2}=\frac{47}{2}\ lb

3\frac{3}{4}\ lb=\frac{3*4+3}{4}=\frac{15}{4}\ lb

\frac{47}{2}:\frac{15}{4}=\frac{47*4}{2*15} =\frac{94}{15}=6.3\ bags

Round up

7 bags

therefore

The minimum number of freezer bags needed to store all the blueberries is 7
