Answer 1

$a-b=10 \\\\ \frac{a}{b}=2,25 \\\\ 2,25\to2 \frac{25}{100}=2\frac{1}{4} =\frac{9}{4} \\\\ \frac{a}{b}=\frac{9}{4} \\\\ 4a=9b \\\\ a=\frac{9b}{4} \\\\\\ \frac{9b}{4}-b^{(4}=10^{(4} \\\\ 9b-4b=40 \\\\ 5b=40 \ |:5 \\\\ \boxed{b=8} \\\\ a=\frac{9*8}{4} \\\\ a=9*2 \\\\ \boxed{a=18}$

Answer 2

a-b=10 $\frac{a}{b} = 2,25$ a:b=2,25 a=b*2,25 b*2,25-b=10 1,25b=10 125b=1000\125 b=8 a=2,25*8 a=18 Cel mai bun raspuns ? Pls
