`7/4 = (7xx3)/(4xx3) = 21/12`

Answer 2

\(\dfrac{5}{3}=\dfrac{5\times4}{3\times4}=\dfrac{20}{12}\)

\(\dfrac{9}{2}=\dfrac{9\times6}{2\times6}=\dfrac{54}{12}\)

\(\dfrac{7}{4}=\dfrac{7\times3}{4\times3}=\dfrac{21}{12}\)

 

Answer 3

\(\text{MSC : 12}\)

\(\dfrac{5}{3}=\dfrac{5\times4}{3\times4}=\dfrac{20}{12}\)

\(\dfrac{\text{9}}{2}=\dfrac{9\times6}{2\times6}=\dfrac{54}{12}\)

\(\dfrac{\text{ 7}}{4}=\dfrac{7\times3}{4\times3}=\dfrac{21}{12}\)
