Question

compare 4 ratio 5 and 7 ratio 9​

Answer 1

Answer:

$\frac{4}{5} = \frac{4 \times 9}{5 \times 9} = \frac{36}{45} \\ \frac{7}{9} = \frac{7 \times 5}{9 \times 5} = \frac{35}{45} \\ \because \: 36 > 35 \\ \therefore \: \frac{36}{45} > \frac{35}{45} \\ \therefore \: \frac{4}{5} > \frac{7}{9}$
