Solution

The correct option is A
9/2

L.C.M of 7 and 8 is 56.

$\frac{3}{7}$ and $\frac{4}{8}$ can be written as $\frac{24}{56}$ and $\frac{28}{56}$

Since the denominator is the same, comparing the numerator , we have

24 < 28

Hence, $\frac{24}{56}$ < $\frac{28}{56}$

$∴$ $\frac{3}{7}$ < $\frac{4}{8}$
