[tex]L.c.m \: \: of \: 5 \: \: and \: \: \: 9 \: is \: 45[/tex]
[tex] = \frac{4}{5} \\ = \frac{4 \times 9}{5 \times 9} \\ = \frac{36}{45} [/tex]
[tex] = \frac{7}{9} \\ = \frac{7 \times 5}{9 \times 5} \\ = \frac{35}{45} [/tex]
[tex] \frac{36}{45} > \frac{35}{45} ⇒ \frac{4}{5} > \frac{7}{9} [/tex]
[tex]⇒ \frac{4}{5} > \frac{7}{9} [/tex]
