Question

\(\dfrac{3}{7}\).\(\left(\dfrac{-5}{6}\right)\)-\(\dfrac{1}{8}\)

Answer 1

\(=-\dfrac{5}{14}-\dfrac{1}{8}=-\dfrac{20}{56}-\dfrac{7}{56}=-\dfrac{27}{56}\)

Answer 2

\(\dfrac{3}{7}.\left(\dfrac{-5}{6}\right)-\dfrac{1}{8}\\ =\dfrac{-5}{14}-\dfrac{1}{8}\\ =\dfrac{-5.8}{14.8}-\dfrac{1.14}{8.14}\\ =\dfrac{-40}{112}-\dfrac{14}{112}\\ =\dfrac{-40-14}{112}\\ =\dfrac{-54}{112}\\ =\dfrac{-27}{56}.\)

Thank you Vinamilk:)

Answer 4

`3/7 . (-5)/6 - 1/8`

` = (3xx-5)/(7xx6) - 1/8`

` = (-5)/14 - 1/8`

` = (-20)/56 - 7/56`

`= (-27)/56`
