Answer 1

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

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},\\\\\text{ she need }(3)/(4)\text{ pound of blueberries }\\\\\text{ For 1 cup of jam}.\\\\\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 .
