Answer 1

Răspuns:

$1) \\ a) \frac{2}{3} - \frac{1}{5} = \frac{10 - 3}{15} = \frac{7}{15} \\ b) \frac{5}{2} - \frac{2}{5 } = \frac{25 - 4}{10} = \frac{21}{10} \\ 2) \\ a) \frac{5}{3} - \frac{1}{12} - \frac{3}{4} = \frac{20 - 1 - 9}{12} = \frac{10}{12} \\ b) \frac{8}{7} + \frac{12}{21} - \frac{1}{4} = \frac{96 + 48 - 21}{84} = \frac{123}{84}$
