Answer 1

Respuesta:

$a) \frac{3}{2} + 4 - \frac{7}{4} = \frac{6}{4} + \frac{16}{4} - \frac{7}{4} = \frac{15}{4}$

$b) \frac{10}{3} - \frac{11}{6} + 9 = \frac{20}{6} - \frac{11}{6} + \frac{54}{6} = \frac{63}{6} = \frac{21}{2}$

$c) \frac{3}{4} + 5 - \frac{1}{8} = \frac{6}{8} + \frac{40}{8} - \frac{1}{8} = \frac{45}{8}$

$d) \frac{7}{2} - \frac{7}{4} - \frac{7}{8} = \frac{28}{8} - \frac{14}{8} - \frac{7}{8} = \frac{7}{8}$

$e) \frac{8}{9} + \frac{16}{15} - \frac{2}{15} = \frac{40}{45} + \frac{48}{45} - \frac{6}{45} = \frac{82}{45}$

$f) \frac{9}{7} + \frac{9}{14} + 2 = \frac{18}{14} + \frac{9}{14} + \frac{28}{14} = \frac{55}{14}$

$g) \frac{15}{8} - \frac{3}{4} + \frac{3}{10} = \frac{75}{40} - \frac{30}{40} + \frac{12}{40} = \frac{57}{40}$

$h)3 - \frac{5}{12} + \frac{13}{6} = \frac{36}{12} - \frac{5}{12} + \frac{26}{12} = \frac{57}{12} = \frac{19}{4}$
