Answer 1

Respuesta:

$\frac{1}{2} + \frac{6}{7} = \frac{12 + 7}{14} = \frac{19}{12}$

$\frac{2}{5} + \frac{7}{8} = \frac{35 + 16}{40} = \frac{51}{40}$

$\frac{3}{4} + \frac{1}{8} = \frac{4 + 24}{32} = \frac{28}{32} = \frac{7}{8}$

$\frac{9}{4} - \frac{4}{7} = \frac{63 - 16}{28} = \frac{47}{28}$

$\frac{2}{3} + \frac{5}{7} = \frac{14 + 15}{21} = \frac{29}{21}$

$\frac{3}{10} - \frac{1}{12} = \frac{18 - 5}{60} = \frac{13}{60}$

$\frac{5}{6} + \frac{1}{4} = \frac{6 + 20}{24} = \frac{26}{24} = \frac{13}{12}$

$\frac{2}{4} + \frac{9}{2} = \frac{4 + 36}{8} = \frac{40}{8} = 5$

$\frac{2}{3} - \frac{2}{5} = \frac{10 - 6}{15} = \frac{4}{15}$
