Chase is making calzones that require 2 3/4 pounds of beef. he only has 1,1/6 pound left. how much more does he need?
a. 1 7/12
b. 1 1/6
c. 5/6
d. 11/12

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.

I'm not sure but i think it's 1670km/h
