Question

Answer 1

\(9,\dfrac{-1}{12}+\dfrac{-5}{6}-\dfrac{4}{3}=\dfrac{-1}{12}+\dfrac{-10}{12}+\dfrac{-16}{12}=\dfrac{-\left(1+10+16\right)}{12}=\dfrac{5}{12}\)

\(10,\dfrac{-7}{8}+\dfrac{2}{3}-\dfrac{5}{12}=\dfrac{-21}{24}+\dfrac{16}{24}-\dfrac{10}{24}=\dfrac{\left(-21\right)+16-10}{24}=\dfrac{-15}{24}=\dfrac{-5}{8}\)
