4/21 + (- 3/7 ) +5/14 =​

Answer 1

$\frac{4}{21} + ( - \frac{3}{7} ) + \frac{5}{14} \\ \\ \frac{4}{21} - \frac{3}{7} + \frac{5}{14} \\ \\ \frac{4 \times 2}{21 \times 2} - \frac{3 \times 6}{7 \times 6} + \frac{5 \times 3}{14 \times 3} \\ \\ \frac{8}{42} - \frac{18}{42} + \frac{15}{42} \\ \\ \frac{8 - 18 + 15}{42} \\ \\ \frac{5}{42}$
