Question

Efectúa la operación 5/7+1/4x2/5-4/6​

Answer 1

Respuesta:

$\frac{5}{7} + \frac{1}{4} \times \frac{2}{5} - \frac{4}{6} \\ \frac{5}{7} + \frac{(1 \times 2)}{(4 \times 5)} - \frac{4}{6} \\ \frac{5}{7} + \frac{2}{20} - \frac{4}{6} \\ \frac{5}{7} + \frac{1}{10} - \frac{2}{3} \\ \frac{50 + 7}{70} - \frac{2}{3}$

$\frac{57}{70} - \frac{2}{3} \\ \frac{171 - 140}{210} \\ \frac{31}{210}$
