Question

\(-3+\dfrac{2}{5}=\)

\(\dfrac{-312}{936}+\dfrac{-373737}{151515}=\)

\(\dfrac{-3}{8}-\dfrac{5}{12}=\)

Answer 1

\(-3+\dfrac{2}{5}=\dfrac{-13}{5}\)

\(\dfrac{-312}{936}+\dfrac{-373737}{151515}=\dfrac{-14}{5}\)

\(\dfrac{-3}{8}-\dfrac{5}{12}=\dfrac{-19}{24}\)

Answer 2

\(-3+\dfrac{2}{5}=\dfrac{-15}{5}+\dfrac{2}{5}=\dfrac{-13}{5}\\ \dfrac{-312}{936}+\dfrac{-373737}{151515}=\dfrac{-1}{3}+\dfrac{-37}{15}=\dfrac{-5}{15}+\dfrac{-37}{15}=\dfrac{-42}{15}=\dfrac{-14}{5}\)

\(\dfrac{-3}{8}-\dfrac{5}{12}=\dfrac{-9}{24}-\dfrac{10}{24}=\dfrac{-19}{24}\)
