\(\dfrac{2}{8}\)=\(\dfrac{9}{36}\); \(\dfrac{8}{2}\)=\(\dfrac{36}{9}\); \(\dfrac{2}{9}\)=\(\dfrac{8}{36}\); \(\dfrac{9}{2}\)=\(\dfrac{36}{8}\)

x = 5

y = 14

z = 12

\(\dfrac{2}{4}\)=\(\dfrac{4}{8}\)=\(\dfrac{8}{16}\)=\(\dfrac{16}{32}\)

\(\dfrac{2}{8}\)=\(\dfrac{4}{16}\) =\(\dfrac{8}{32}\)

\(\dfrac{2}{16}\)=\(\dfrac{4}{32}\)
