Answer:
[tex]\frac{1}{4}[/tex] pounds of blueberries he need to buy more.
Step-by-step 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:
[tex]3\ pounds-2\frac{3}{4} \ pounds[/tex]
[tex]=3-\frac{11}{4}[/tex]
[tex]=\frac{12-11}{4}[/tex]
[tex]=\frac{1}{4} \ pounds.[/tex]
Therefore, [tex]\frac{1}{4}[/tex] pounds of blueberries he need to buy more.
