Question

Answer 1

\(d,=\left(\dfrac{3}{4}-\dfrac{1}{4}\right):\left(-5\right)+\dfrac{1}{15}-\left(-\dfrac{1}{5}\right):\left(-3\right)\\ =\dfrac{1}{2}.\dfrac{-1}{5}+\dfrac{1}{15}-\dfrac{1}{15}\\ =-\dfrac{1}{10}+0\\ =-\dfrac{1}{10}\)

Answer 2

\(=\dfrac{1}{2}\cdot\dfrac{1}{-5}+\dfrac{1}{15}-\dfrac{1}{15}=\dfrac{-1}{10}\)
