Answer 1

Răspuns:

$a)\frac{ - 3}{5} + \frac{7}{5} = \frac{4}{5}$

$b)\frac{14}{3} + ( - \frac{5}{3} ) = 3$

$c)- \frac{12}{7} - \frac{3}{7} = - \frac{15}{7}$

$d) - \frac{45}{8} + \frac{45}{8} = 0$

$e) \frac{2}{3} + \frac{1}{2} = \frac{7}{6}$

$f) - \frac{13}{2} + \frac{1}{5} = - \frac{63}{10}$

$g) 0.(3) - \frac{1}{3} = 0$

$h)5 - \frac{11}{2} = - \frac{1}{2}$
