Answer 1

Respuesta:

$a) \frac{2}{9} + \frac{5}{18} = \frac{4}{18} + \frac{5}{18} = \frac{9}{18} = \frac{1}{2}$

$b) \frac{3}{10} + \frac{8}{15} = \frac{9}{30} + \frac{16}{30} = \frac{25}{30} = \frac{5}{6}$

$c) \frac{5}{8} + \frac{1}{24} = \frac{15}{24} + \frac{1}{24} = \frac{16}{24} = \frac{2}{3}$

$d) \frac{1}{4} - \frac{1}{12} = \frac{3}{12} - \frac{1}{12} = \frac{2}{12} = \frac{1}{6}$

$e) \frac{3}{5} - \frac{1}{10} = \frac{6}{10} - \frac{1}{10} = \frac{5}{10} = \frac{1}{2}$

$f) \frac{5}{6} - \frac{3}{10} = \frac{25}{30} - \frac{9}{30} = \frac{16}{30} = \frac{8}{15}$
