Question

5/6x7/12+5/12x5/6+1/6

Answer 1

\(\frac{5}{6}\times\frac{7}{12}+\frac{5}{12}\times\frac{5}{6}+\frac{1}{6}=\frac{5}{6}\times\left(\frac{7}{12}+\frac{5}{12}\right)+\frac{1}{6}=\frac{5}{6}+\frac{1}{6}=1\)

Answer 2

Answer 3

\(\frac{5}{6}.\frac{7}{12}+\frac{5}{12}.\frac{5}{6}+\frac{1}{6}\)

\(=\frac{5}{6}.\left(\frac{7}{12}+\frac{5}{12}\right)+\frac{1}{6}\)

\(=\frac{5}{6}.1+\frac{1}{6}\)

\(=\frac{5}{6}+\frac{1}{6}\)

\(=1\)
