Respuesta:
[tex] \frac{5}{6} [/tex]
Explicación paso a paso:
[tex]m = \frac{1}{2} \: \: n = \frac{1}{3} [/tex]
[tex]m + n = \frac{1}{2} + \frac{1}{3} [/tex]
[tex] \frac{1}{2} + \frac{1}{3} = \frac{1 \times 3 + 2 \times 1}{2 \times 3} [/tex]
[tex] \frac{3 + 2}{6} = \frac{5}{6} [/tex]
[tex] \frac{5}{6} = 0.8333333333..[/tex]
