Răspuns:

$1.1(6) = 1 \frac{16 - 1}{90} = 1 \frac{15}{90} = 1 \frac{1}{6} = \frac{7}{6}$

$0.5 = \frac{1}{2}$

$1 \frac{1}{4} = \frac{5}{4}$

$0.(6) = \frac{6}{9} = \frac{2}{3}$

$2 \frac{1}{4} = \frac{9}{4}$

$\frac{1}{2} - \frac{5}{4} = - \frac{3}{4}$

$\frac{2}{3} - \frac{9}{4} = - \frac{19}{12}$

$- \frac{3}{4} + \frac{19}{12} = \frac{10}{12} = \frac{5}{6}$

$\frac{7}{6} - \frac{5}{6} = \frac{2}{6} = \frac{1}{3}$
