Here is the solution of the given problem above.
Firstly, to make the solution easier, let us convert the mixed fractions.
2 3/4 is 11/4 (Pounds of beef needed)
1 1/6 is 7/6 (Pounds of beef available)
So, to get how much more he needs, we will deduct 7/6 from 11/4 and we get 19/12. And this fraction is equivalent to option A. 1 7/12. Therefore, he needs 1 7/12 pounds more. hope this answer helps.

Answer:

Option A is the correct answer.

Step-by-step explanation:

Chase is making calzones that require 2 3/4 pounds of beef.

[tex]\texttt{Beef required for making calzones  = }2\frac{3}{4}=\frac{2\times 4+3}{4}=\frac{11}{4}pounds[/tex]

Chase only has 1 1/6 pound left.

[tex]\texttt{Beef chase has = }1\frac{1}{6}=\frac{1\times 6+1}{6}=\frac{7}{6}pounds[/tex]

[tex]\texttt{Extra beef required = }\frac{11}{4}-\frac{7}{6}=\frac{66-28}{24}\\\\\texttt{Extra beef required = }\frac{38}{24}\\\\\texttt{Extra beef required = }\frac{19}{12}=\frac{12+7}{12}=1+\frac{7}{12}\\\\\texttt{Extra beef required = }1\frac{7}{12}[/tex]

Option A is the correct answer.
