Question

\(\dfrac{7}{8}\) : \(\left(\dfrac{2}{9}-\dfrac{1}{18}\right)\) + \(\dfrac{7}{8}:\left(\dfrac{1}{36}-\dfrac{5}{12}\right)\)

 

Answer 1

\(\dfrac{7}{8}:\left(\dfrac{2}{9}-\dfrac{1}{18}\right)+\dfrac{7}{8}:\left(\dfrac{1}{36}-\dfrac{5}{12}\right)\)

\(\dfrac{7}{8}:\dfrac{1}{6}+\dfrac{7}{8}:\dfrac{-14}{36}\)

\(\dfrac{7}{8}:\dfrac{1}{6}+\dfrac{7}{8}:\dfrac{-7}{18}\)

\(\dfrac{7}{8}.6+\dfrac{7}{8}.\dfrac{-18}{7}\)

\(\dfrac{7}{8}.\left(6+\dfrac{-18}{7}\right)\)

\(\dfrac{7}{8}.\left(\dfrac{42}{7}+\dfrac{-18}{7}\right)\)

\(\dfrac{7}{8}.\dfrac{24}{7}\)

\(\dfrac{24}{3}=3\)
