[hallamos la suma y resta de fracciones]

$\bf \: \frac{6}{7} + \frac{7}{12} = \frac{72 + 49}{84} = \frac{121}{84} \\ \bf \:1 \frac{1}{8} + \frac{7}{12} = \frac{9}{8} + \frac{7}{12} = \frac{41}{24} \\ \bf \: \frac{2}{9} + \frac{1}{3} + \frac{5}{6} - \frac{1}{12} = \frac{8 + 12 + 30 - 3}{36} = \frac{47}{3} \\ \bf \:3 \frac{7}{12} + 5 \frac{2}{3} = (3 + 5) + ( \frac{7}{12} + \frac{2}{3} ) = 8 + \frac{7}{12} + \frac{2}{3} ) = 8 + \frac{5}{4} = 8 + 1 \frac{1}{4} = 8 + 1 + \frac{1}{4} = 9 + \frac{1}{4} = 9 \frac{1}{4}$
