5/6+1,3+1/6+0,7​

Answer 1

$\frac{1}{7} - \frac{6}{7} = - \frac{5}{7} \\ \frac{5}{6} - \frac{1}{3} = \frac{5 - 2}{6} = \frac{3}{6} = \frac{1}{2} \\ \frac{3}{4} - \frac{1}{4} = \frac{2}{4} = \frac{1}{2} \\ \frac{1}{3} + \frac{1}{3} + \frac{1}{3} = \frac{3}{3} = 1$

$\frac{1}{2} + \frac{1}{2} = \frac{2}{2} = 1 \\ \frac{5}{6} + \frac{13}{10} + \frac{1}{6} + \frac{7}{10} = \frac{6}{6} + \frac{20}{10} = 1 + 2 = 3$
