Answer 8

\(a,\dfrac{8}{12}=\dfrac{8:4}{12:4}=\dfrac{2}{3};\dfrac{20}{48}=\dfrac{20:4}{48:4}=\dfrac{5}{12};\dfrac{74}{100}=\dfrac{74:2}{100:2}=\dfrac{37}{50};\dfrac{18}{21}=\dfrac{18:3}{21:3}=\dfrac{6}{7};\dfrac{40}{54}=\dfrac{40:2}{54:2}=\dfrac{20}{27};\dfrac{30}{45}=\dfrac{30:5}{45:5}=\dfrac{6}{9}=\dfrac{2}{3}\)

Answer 9

a,

8/12=\(\dfrac{8}{12}=\dfrac{8:4}{12:4}=\dfrac{2}{3}\)

20/48=\(\dfrac{20}{48}=\dfrac{20:4}{48:4}=\dfrac{5}{12}\)

74/100=\(\dfrac{74}{100}=\dfrac{74:2}{100:2}=\dfrac{37}{50}\)

18/21=\(\dfrac{18}{21}=\dfrac{18:3}{21:3}=\dfrac{6}{7}\)

40/54=\(\dfrac{40}{54}=\dfrac{40:2}{54:2}=\dfrac{20}{27}\)

30/45=\(\dfrac{30}{45}=\dfrac{30:3}{45:3}=\dfrac{10}{15}\)
