[tex]d)1 + \frac{5}{6} = \frac{6 + 5}{6} = \frac{11}{6} \\ \frac{2}{3} + 1 = \frac{2 + 3}{3} = \frac{5}{3} \\ 1 + \frac{3}{10} = \frac{10 + 3}{10} = \frac{13}{10} \\ 1 - \frac{2}{3} = \frac{3 - 2}{3} = \frac{1}{3} \\ \frac{7}{5} - 1 = \frac{7 - 5}{5} = \frac{2}{5} \\ \frac{18}{7} - 1 = \frac{18 - 7}{7} = \frac{11}{7} [/tex]
sper că te-am ajutat
