Question

(67/111+2/33-15/117).(1/3-1/4-1/12)

Answer 1

(67/111+2/33-15/117).(1/3-1/4-1/12)=(67/111+2/33-15/117).0=0

Answer 2

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

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

= \(\left(\frac{67}{111}+\frac{2}{33}-\frac{15}{117}\right).0\)

= \(0\)

Answer 3

= 0
