Question

2/5 ×-3/7 -1/6×3/2+1/14×2/5​

Answer 1

Step-by-step explanation:

$\frac{2}{5} \times - \frac{3}{7} - \frac{1}{6} \times \frac{3}{2} + \frac{1}{14} \times \frac{2}{5}$

$- \frac {6}{ 35} - \frac{3}{12} + \frac{2}{70}$

TALE L. C .M .

$- \frac{6(12) - 3(35) + 2(6)}{420}$

$- \frac{72 - 105 + 12}{420}$

$- \frac{165}{420}$

$- \frac{11}{28}$
