Answer 2

\(C=\left(\frac{67}{111}+\frac{2}{33}-\frac{15}{117}\right)x\left(\frac{1}{3}-\frac{1}{4}-\frac{1}{12}\right)\)

\(\Rightarrow C=\left(\frac{67}{111}+\frac{2}{33}-\frac{15}{117}\right)x\left(\frac{1}{12}-\frac{1}{12}\right)\)

\(\Rightarrow C=\left(\frac{67}{11}+\frac{2}{33}-\frac{15}{117}\right)x0\)

\(\Rightarrow C=0\)

Answer 3

C=(67/111 +2/33 −15/117 )x(1/3 −1/4 −1/12 )

= 1/3 - 1/4 - 1/12 = 0

mà bao nhiêu nhân 0 vẫn bằng 0

vậy C = 0
