Question

Simplify:-
$4\frac{1}{2}-1\frac{4}{5}$

Answer 1

$41/2-14/5$

$=\frac{\left(2\right)\left(4\right)+1}{2}\frac{\left(5\right)\left(1\right)+4}{5}$

$=\frac{9}{2}-\frac{9}{5}$

$=\frac{\left(9\right)\left(5\right)-\left(9\right)\left(2\right)}{\left(5\right)\left(2\right)}$

$=\frac{45-8}{10}$

$=\frac{27}{10}$

$=\frac{20}{10}+\frac{7}{10}$

$=2+\frac{7}{10}$

$=2\frac{7}{10}$
