Question

Compare the fractions given below:
$\frac{4}{5},\frac{7}{10}$

Answer 1

L.C.M. of 5 and 10 = (5 $\times$ 2) = 10
Now, we convert $\frac{4}{5}$ into an equivalent fraction having 10 as the denominator as the other fraction has already 10 as its denominator.
∴​ $\frac{4}{5}=\frac{4\times 2}{5\times 2}=\frac{8}{10}$4949

Clearly, $\frac{8}{10}>\frac{7}{10}$
$\therefore$ $\frac{4}{5}>\frac{7}{10}$
