ayudaaaaaa no entiendo xD poooorrrr faaaavooooorrrr​

Answer 1

Respuesta:

$\frac{15}{12} - (\frac{5}{12} + \frac{2}{12}) = \frac{15}{12} - \frac{7}{12} = \frac{8}{12} = \frac{2}{3}$

$\frac{12}{7} - \frac{15}{7} + \frac{5}{7} = -\frac{3}{7} + \frac{5}{7} = \frac{2}{7}$

$(\frac{9}{8} - \frac{7}{8}) + \frac{10}{8} = \frac{2}{8} + \frac{10}{8} = \frac{12}{8} = \frac{3}{2}$

Espero que te ayude
