Question

\(16\dfrac{2}{7}\) : \(-\dfrac{3}{5}\) + \(28\dfrac{2}{7}\) : \(\dfrac{3}{5}\)

Answer 1

\(16\dfrac{2}{7}:\dfrac{-3}{5}+28\dfrac{2}{7}:\dfrac{3}{5}\)

\(=\left(-16-\dfrac{2}{7}\right):\dfrac{3}{5}+\left(28+\dfrac{2}{7}\right):\dfrac{3}{5}\)

\(=\left(-16-\dfrac{2}{7}+28+\dfrac{2}{7}\right):\dfrac{3}{5}=12:\dfrac{3}{5}=20\)
