Answers

Answer: She needed $1(1)/(2)\text{ pounds of blueberries}$ to make a cup of jam .

Step-by-step explanation:

Since we have given that

Sarah used $(3)/(4)$ pound of blueberries to make $(1)/(2)$ cup of jam.

As we need to find the number of pounds of blueberries she would need to make a cup of jam.

So, we will use "Unitary Method":

$\text{For }(1)/(2)\text{ cup of jam},\n\n\text{ she need }(3)/(4)\text{ pound of blueberries }\n\n\text{ For 1 cup of jam}.\n\n\text{She need }=(3)/(4)* 2=(3)/(2)=1(1)/(2)\text{ pounds of blueberries }$

Hence, She needed $1(1)/(2)\text{ pounds of blueberries}$ to make a cup of jam .
