Question

-11/4 - 3/2 +17/3 = ...

Answer 1

$-\frac{11}{4} - \frac{3}{2} + \frac{17}{3} = \\ \\ -\frac{33}{12} - \frac{18}{12}+ \frac{61}{12} = \\ \\ =\frac{10}{12} = \frac{5}{6} \\ \\ -\frac{11}{4} - \frac{3}{2} + \frac{17}{3}= \frac{5}{6}$
am adus la acelasi numitor (12) amplificand fiecare fractie corespunzator , apoi am simplificat pana la obtinerea unei fractii ireductibile
