\(=1-\dfrac{5}{6}=\dfrac{6}{6}-\dfrac{5}{6}=\dfrac{1}{6}\)
\(\dfrac{6}{7}:\dfrac{12}{14}-\dfrac{5}{6}=\dfrac{6}{7}.\dfrac{14}{12}-\dfrac{5}{6}=1-\dfrac{5}{6}=\dfrac{6}{6}-\dfrac{5}{6}=\dfrac{1}{6}\)
`6/7:12/14- 5/6=6/7 × 14/12 -5/6 = 2/2 - 5/6 = 1 - 5/6 = 1/6`
\(\dfrac{6}{7}\) : \(\dfrac{12}{14}\) - \(\dfrac{5}{6}\) = \(\dfrac{6}{7}\) x \(\dfrac{14}{12}\) - \(\dfrac{5}{6}\) = 1 - \(\dfrac{5}{6}\) = \(\dfrac{6}{6}\) - \(\dfrac{5}{6}\) = \(\dfrac{1}{6}\)
