Question

Solve:

$4\frac{3}{8}-\frac{25}{18}$.

Answer 1

$4\frac{3}{8}-\frac{25}{18}$

$\frac{35}{8}-\frac{25}{18}$

L.C.M. of $8$ and $18$ is

$2\times 2\times 2\times 3\times 3$

$=72$

$\frac{(35\times 9)-(25\times 4)}{72}$

$\frac{5(7\times 9-5\times 4)}{72}$

$\frac{5(63-20)}{72}$

$\frac{5\times 43}{72}$

$=\frac{215}{72}$

$=2\frac{71}{72}$
