Question

Va rog urgent daca se poate ex 7 dau coroana

Answer 1

$\frac{8}{7} - \frac{3}{14} = \frac{16}{14} - \frac{3}{14} = \frac{13}{14}$

$\frac{6}{5} + \frac{9}{10} = \frac{12}{10} + \frac{9}{10} = \frac{21}{10}$

$\frac{1}{3} - \frac{2}{9} = \frac{3}{9} - \frac{2}{9} = \frac{1}{9}$

$\frac{9}{10} - \frac{2}{6} = \frac{27}{30} - \frac{10}{30} = \frac{17}{30}$

$\frac{8}{3} + \frac{1}{12} = \frac{32}{12} + \frac{1}{12} = \frac{33}{12}$

$\frac{2}{3} - \frac{4}{6} = \frac{4}{6} - \frac{4}{6} =0$

$\frac{5}{12} - \frac{1}{3} = \frac{5}{12} - \frac{4}{12} = \frac{1}{12}$

$\frac{6}{8} + \frac{8}{6} = \frac{18}{24} + \frac{32}{24} = \frac{50}{24}$

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