Answer 1

Respuesta:

a) $\frac{31}{7}$

b) $\frac{13}{5}$

c) 1

Explicación paso a paso:

a) $\frac{15}{7} + \frac{12}{7} + \frac{4}{7}$ = $\frac{15+12+4}{7}$ =$\frac{31}{7}$

b) $\frac{14}{5} + \frac{8}{5} - \frac{9}{5}$ = $\frac{14+8-9}{5} =$ $\frac{13}{5}$

c) $(\frac{4-8}{6}) + (\frac{1+9}{6})$ = $\frac{-4}{6} + \frac{10}{6} = \frac{-4+10}{6} = \frac{+6}{6} =1$
