Question

5/6 - (1/3 + 1/2) x 20%

Answer 1

\(\dfrac{5}{6}-\left(\dfrac{1}{3}+\dfrac{1}{2}\right)\times20\%=\dfrac{5}{6}-\left(\dfrac{2}{6}+\dfrac{3}{6}\right)\times20\%=\dfrac{5}{6}-\dfrac{5}{6}\times20\%=\dfrac{5}{6}\times\left(1-\dfrac{1}{5}\right)=\dfrac{5}{6}\times\dfrac{4}{5}=\dfrac{20}{30}=\dfrac{2}{3}\)

Answer 2

\(\dfrac{5}{6}-\left(\dfrac{1}{3}+\dfrac{1}{2}\right)\times20\%\\ =\dfrac{5}{6}-\left(\dfrac{2}{6}+\dfrac{3}{6}\right)\times\dfrac{1}{5}\\ =\dfrac{5}{6}-\dfrac{5}{6}\times\dfrac{1}{5}\\ =\dfrac{5}{6}-\dfrac{1}{6}\\ =\dfrac{2}{3}\)
