Question

Answer 1

\(a,\dfrac{3}{2}=\dfrac{9}{6};\dfrac{3}{9}=\dfrac{2}{6};\dfrac{9}{3}=\dfrac{6}{2};\dfrac{2}{3}=\dfrac{6}{9}\)

\(b,\dfrac{-2,5}{5}=\dfrac{-1,5}{3};\dfrac{-2,5}{-1,5}=\dfrac{5}{3};\dfrac{5}{-2,5}=\dfrac{3}{-1,5};\dfrac{-1,5}{-2,5}=\dfrac{3}{5}\)

\(c,\dfrac{12}{-9}=\dfrac{1}{\dfrac{-3}{4}};\dfrac{-9}{12}=\dfrac{-\dfrac{3}{4}}{1};\dfrac{12}{1}=\dfrac{-9}{\dfrac{-3}{4}};\dfrac{1}{12}=\dfrac{\dfrac{-3}{4}}{-9}\)

Answer 2

a) \(\dfrac{3}{2}=\dfrac{9}{6}\)  b) \(\dfrac{-2,5}{-1,5}=\dfrac{5}{3}\)  c) \(\dfrac{\dfrac{-3}{4}}{-9}=\dfrac{1}{12}\)
