Answer 2

Răspuns:

$\frac{9}{5}$

$\frac{8}{7}$

$\frac{11}{7}$

$\frac{22}{100}$

Explicație pas cu pas:

$\frac{4}{5} - \frac{1}{5} + \frac{6}{5} = \frac{3}{5} + \frac{6}{5} = \frac{9}{5}$

$\frac{3}{7} + \frac{7}{7} - \frac{2}{7} = \frac{10}{7} - \frac{2}{7} = \frac{8}{7}$

$\frac{6}{7} - \frac{3}{7} + \frac{8}{7} = \frac{3}{7} + \frac{8}{7} = \frac{11}{7}$

$\frac{5}{100} + \frac{2}{100} + \frac{15}{100} = \frac{7}{100} + \frac{15}{100} = \frac{22}{100}$
