Respuesta:

$1 \frac{2}{3} + 2 \frac{3}{5} + 1 \frac{3}{7} = \\ \\ ( \frac{3 \times 1 + 2}{3} ) + ( \frac{5 \times 2 + 3}{5} ) + ( \frac{7 \times 1 + 3}{7} ) = \\ \\ \frac{5}{3} + \frac{13}{5} + \frac{10}{7} = (\frac{175 + 273 + 150}{105} ) = \frac{598}{105} \\ \\ \frac{598}{105} = 5.69 = 5 \: metros \: y \: 69 \: centimetros \:$
