Answer 1

\(\dfrac{28}{42}=\dfrac{2}{3};\dfrac{60}{45}=\dfrac{4}{3};\dfrac{64}{48}=\dfrac{4}{3};\dfrac{58}{154}=\dfrac{29}{77}\)

Answer 2

\(\dfrac{28}{42}=\dfrac{2}{3}\\ \dfrac{60}{45}=\dfrac{4}{3}\\ \dfrac{64}{48}=\dfrac{4}{3}\\ \dfrac{58}{154}=\dfrac{29}{77}\)

Answer 3

\(\dfrac{28}{42}=\dfrac{28\div14}{42\div14}=\dfrac{2}{3}\)

\(\dfrac{60}{45}=\dfrac{60\div15}{45\div15}=\dfrac{4}{3}\)

\(\dfrac{64}{48}=\dfrac{64\div16}{48\div16}=\dfrac{4}{3}\)

\(\dfrac{58}{154}=\dfrac{58\div2}{154\div2}=\dfrac{29}{77}\)
