Answer 2

Răspuns:

$1. \\ \frac{7}{15} - \frac{3}{15} = \frac{4}{15} - \frac{2}{15} = \frac{2}{15} + \frac{10}{15} = \frac{12}{15} + \frac{3}{15} = \frac{15}{15} = 1 \\ \\ 2. \\ \frac{3}{7} + \frac{}{7} = \frac{9}{} - \frac{5}{7} \\ \frac{3}{7} + \frac{1}{7} = \frac{9}{7} - \frac{5}{7} \\ \\ 3. \\ ( \frac{3}{6} + \frac{4}{6} - 1) + (3 - \frac{2}{6}) = \\ ( \frac{3 + 4 - 6}{6} ) + ( \frac{18 - 2}{6} ) = \\ \frac{1}{6} + \frac{16}{6} = \frac{17}{6}$
