How to solve 3/7+(-6/11)+(-8/21)+5/22
Can you please explain me with calculations and step by step and fast

Answer 1

3/7+(-6/11)+(-8/21)+5/22
=3/7-6/11-8/21+5/22 [-×+=-]
=3/7-8/21-6/11+5/22
=3(3)-8/21-6(2)+5/22
=1/21-17/22
=22-17(21)/462
=22-357/462
=-335/462

Answer 2

={3/7+(-8/21)}+{5/22+(-6/11)}

$= \frac{9 - 8}{21} + \frac{5 - 12}{22}$
$= \frac{1}{21} - \frac{7}{22}$
$= \frac{22 - 147}{21 \times 22}$
$= \frac{ - 125}{462}$
