Answer 1

$10-\frac{3}{9} -14\frac{4}{13} +14\frac{2}{8} =$$9\frac{95}{156}$

$1)10-\frac{3}{9}=\frac{90-3}{9} =9\frac{2}{3}$

$2)9\frac{2}{3}-14\frac{4}{13} = \frac{377-558}{39} =-\frac{181}{39} =-4\frac{25}{39}$

$3)-4\frac{25}{39} +14\frac{2}{8} =-\frac{1448+4446}{312} =\frac{2998}{312} =\frac{1499}{156} =9\frac{95}{156}$
