Answer 1

sa se amplifice fractiile cu 2
1\2=2\4
7\3=14\6
a\b=2a\2b
2x+1\5=4x+2\10
m+2\n-2=2m+4\2n-2
succes

Answer 2

$\displaystyle \frac{1}{2} = \frac{2}{4} \\ \\ \frac{7}{3} = \frac{14}{6} \\ \\ \frac{a}{b} = \frac{2a}{2b} \\ \\ \frac{2x+1}{5} = \frac{4x+2}{10} \\ \\ \frac{m+2}{n-1} = \frac{2m+4}{2n-2}$
