Question

si se sabe que:
A={1 2/3} × {3 2/6} × {1 8/10} y B={1 3/7} × {1 2/5}
calcular“A+B"​

Answer 1

Respuesta:

$a = 1 \frac{2}{3} \times 3 \frac{2}{6} \times 1 \frac{8}{10} = \frac{5}{3} \times \frac{20}{3} \times \frac{18}{3} = \frac{1800}{27} = 66\frac{2}{3} \\ \\ b = 1 \frac{3}{7} \times 1 \frac{2}{5} = \frac{10}{7} \times \frac{7}{5} = \frac{70}{35} = 2 \\ \\ a + b = 66 \frac{2}{3} + 2 = 68 \frac{2}{3}$
