Solution

As we have $8 : 5 a n d 9 : 7 i . e \frac{8}{5} a n d \frac{9}{7}$
Firstly we will make denominators equal.
$\frac{8}{5} = \frac{8 \times 7}{5 \times 7} = \frac{56}{35} a l s o \frac{9}{7} = \frac{9 \times 5}{7 \times 5} = \frac{45}{35}$
As we get $\frac{56}{35} > \frac{45}{35}$
Hence $\frac{8}{5} > \frac{9}{7}$
