Answer 2

Answer:

$\frac{5}{7} \: \: \: \frac{21}{13} \: \: \: \frac{9}{11} \: \: \: \frac{7}{9 } \\ so \: lcm = 9009 \\ \frac{5}{7} \times \frac{1287}{1287} = \frac{6435}{9009 } \\ \frac{21}{13} \times \frac{693}{693} = \frac{14553}{9009} \\ \frac{9}{11} \times \frac{819}{9009} = \frac{7371}{9009}$
