Question

1. Horace buys 2 ¾ pounds of blueberries for a pie. He needs 48 ounces of blueberries for the pie. How many more pounds of blueberries does he need to buy?

Answer 1

`(1)/(4)` pounds of blueberries he need to buy more.

Explanation:

Given:

Horace buys 2 ¾ pounds of blueberries for a pie.

He needs 48 ounces of blueberries for the pie.

Now, to find pounds of blueberries he need to buy more.

Number of pounds Horace buys blueberries for the pie = 2 ¾ pounds.

He needs blueberries for the pie = 48 ounces.

Now, by using conversion factor convert ounces into pounds:

1 ounce = 0.0625 pounds.

48 ounces = 0.0625 × 48 pounds.

48 ounces = 3 pounds.

Horace needs blueberries for the pie = 3 pounds.

Now, to get the pounds of blueberries he need to buy more we subtract number of pounds Horace buys blueberries for the pie from Horace needs blueberries for the pie:

`3\ pounds-2(3)/(4) \ pounds`

`=3-(11)/(4)`

`=(12-11)/(4)`

`=(1)/(4) \ pounds.`

Therefore,
`(1)/(4)` pounds of blueberries he need to buy more.
