Question

Answer 1

a: \(\dfrac{-2}{3}=\dfrac{-4}{6}=\dfrac{10}{-15}=\dfrac{-12}{18}=\dfrac{20}{-30}=\dfrac{-20}{30}=\dfrac{-40}{60}\)

b: \(\dfrac{5}{6}=\dfrac{10}{12}=\dfrac{20}{24}=\dfrac{-25}{-30}=\dfrac{-40}{-48}=\dfrac{45}{54}=\dfrac{90}{108}\)

c: \(\dfrac{-5}{7}=\dfrac{15}{-21}=\dfrac{-20}{28}=\dfrac{45}{-63}=\dfrac{-40}{56}=\dfrac{-70}{98}=\dfrac{-60}{84}\)

Answer 2

\(a,\dfrac{-2}{3}=\dfrac{-4}{6}=\dfrac{10}{-15}=\dfrac{-12}{18}=\dfrac{20}{-30}=\dfrac{-20}{30}=\dfrac{-40}{60}\\ b,\dfrac{5}{6}=\dfrac{10}{12}=\dfrac{20}{24}=\dfrac{-25}{-30}=\dfrac{-40}{-48}=\dfrac{45}{54}=\dfrac{90}{108}\\ c,\dfrac{-5}{7}=\dfrac{15}{-21}=\dfrac{-20}{28}=\dfrac{45}{-63}=\dfrac{-40}{56}=\dfrac{-70}{98}=\dfrac{-60}{84}\)
