Question

Answer 1

d: \(\frac{-4}{7}=\frac{-4\cdot9}{7\cdot9}=\frac{-36}{63}\)

\(\frac89=\frac{8\cdot7}{9\cdot7}=\frac{56}{63}\)

\(\frac{-10}{21}=\frac{-10\cdot3}{21\cdot3}=\frac{-30}{63}\)

e: \(\frac{-3}{5}=\frac{-3\cdot6}{5\cdot6}=\frac{-18}{30}\)

\(\frac{5}{-6}=\frac{-5}{6}=\frac{-5\cdot5}{6\cdot5}=\frac{-25}{30}\)

\(3=\frac{3\cdot30}{1\cdot30}=\frac{90}{30}\)

f: \(\frac{5}{14}=\frac{5\cdot10}{14\cdot10}=\frac{50}{140}\)

\(\frac{3}{20}=\frac{3\cdot7}{20\cdot7}=\frac{21}{140}\)

\(\frac{9}{70}=\frac{9\cdot2}{70\cdot2}=\frac{18}{140}\)
