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

[tex]2\frac{3}{4}   = 2 + \frac{3}{4}  = 2 + 0.75= 2.75[/tex]

So, the total available beef = 2.75 pounds

Now, [tex]\textrm{ Number of burgers made}  = \frac{\textrm{Weight of available beef}}{\textrm{Beef used in 1 hamburger}}[/tex]

= [tex]\frac{2.75}{0.25}   = 11[/tex]

So, the total number of hamburgers made = 11

Hence,  11   1/4- pounds hamburgers can be made from 2 and 3/4 pounds of ground beef.
