Question

a \(\dfrac{5}{4}\).\(\dfrac{-12}{7}\)

b \(\dfrac{-4}{3}\):\(\dfrac{13}{9}\)

c \(\dfrac{-5}{7}\).\(\dfrac{49}{3}\):\(\dfrac{7}{-6}\)

d (\(-\dfrac{9}{25}\)):6

Answer 1

\(a)\dfrac{5}{4}.\dfrac{-12}{7}=\dfrac{5.\left(-12\right)}{4.7}=\dfrac{-60}{28}=\dfrac{-15}{7}\)

\(b)\dfrac{-4}{3}:\dfrac{13}{9}=\dfrac{-4}{3}.\dfrac{9}{13}=\dfrac{\left(-4\right).9}{3.13}=\dfrac{-36}{39}=\dfrac{-12}{13}\)

\(c)\dfrac{-5}{7}.\dfrac{49}{3}:\dfrac{7}{-6}=\dfrac{-5}{7}.\dfrac{49}{3}:\dfrac{-7}{6}=\dfrac{-35}{3}.\dfrac{-6}{7}=10\)

\(d)\left(-\dfrac{9}{25}\right):6=\dfrac{-3}{50}\)
