Answer 1

`6/10=(6:2)/(10:2)=3/5`

`70/90=(70:10)/(90:10)=7/9`

`96/72=(96:24)/(72:24)=4/3`

`45/35=(45:5)/(35:5)=9/7`

Answer 2

\(\dfrac{6}{10}=\dfrac{6:2}{10:2}=\dfrac{3}{5}\)

\(\dfrac{70}{90}=\dfrac{70:10}{90:10}=\dfrac{7}{9}\)

\(\dfrac{96}{72}=\dfrac{96:24}{72:24}=\dfrac{4}{3}\)

\(\dfrac{45}{35}=\dfrac{45:5}{35:5}=\dfrac{9}{7}\)

Answer 3

6/10=3/5

70/90=7/9

96/72=4/3
