Answer:
11 1/4- pounds hamburgers can be made from 2 and 3/4 pounds of ground beef.
Step-by-step explanation:
Here, the amount of beef uses in 1 hamburger = 1/4 pound = 0.25 pounds
Total amount of beef available = 2 3/4 pounds
Now, solving the mixed fraction,we get
So, the total available beef = 2.75 pounds
Now,
=
So, <u>the total number of hamburgers made = 11 </u>
Hence, 11 1/4- pounds hamburgers can be made from 2 and 3/4 pounds of ground beef.
