[tex] \frac{1}{4} + \frac{1}{8} = \frac{2}{8} + \frac{1}{8} = \frac{2 + 1}{8} = \frac{3}{8} \\ \frac{2}{3} + \frac{5}{6} = \frac{4}{6} + \frac{5}{6} = \frac{4 + 5}{6} = \frac{9}{6} = \frac{3}{2} \\ \frac{2}{7} + 14 = \frac{2}{7} + \frac{98}{7} = \frac{2 + 98}{7} = \frac{100}{7} [/tex]
Sper că te-am ajutat! ^^
