[tex]\frac{5}{8} + ( - \frac{1}{2} ) + ( - \frac{1}{4} ) = \frac{5}{8} - \frac{1}{2} - \frac{1}{4} = \frac{5}{8} - \frac{4}{8} - \frac{2}{8} = \frac{5 - 4 - 2}{8} = - \frac{1}{8} [/tex]
Răspuns:
[tex] \frac{5}{8} + ( - \frac{1}{2} ) + ( - \frac{1}{4} ) \\ aducem \: la \: acelasi \: numitor \: amplificand \: fractiile \\ \frac{5}{8} - \frac{4}{8} - \frac{2}{8} = - \frac{1}{8} [/tex]
Sper că te-am ajutat! ^^
