Answer:

D. 3 1/12

Step-by-step explanation:


\rightarrow \sf 4(1)/(3) -1(1)/(4)

convert into improper fraction


\rightarrow \sf (13)/(3) -(5)/(4)

make the denominators same. 12 is the common factor of both 3 and 4


\rightarrow \sf (13(4))/(12) -(5(3))/(12)

simplify


\rightarrow \sf (52)/(12) -(15)/(12)

join both fraction


\rightarrow \sf (52-15)/(12)

simplify


\rightarrow \sf (37)/(12)

convert into mixed fraction


\rightarrow \sf 3(1)/(12)
