Question

3/7+(-6/13)+(-8/21)+5/21​

Answer 1

Answer:

3/7+(-6/13)+(-8/21)+5/21

= 3/7 - 6/13 - 8/21 + 5/21

= 117/273 - 126/273 - 104/273 + 65/273.

= (117 - 126 - 104 + 65)/273

= -48/ 273 Ans.

Hope this helps ☺️

$\huge\boxed{\underline{\bf { \red S \green O \pink L \blue U \orange T \purple I \red O \pink N \green{..}}}}$

$\longmapsto \sf \frac{3}{7} + \bigg( - \frac{6}{13} \bigg) + \bigg( - \frac{8}{21} \bigg) + \frac{5}{21}$

$\longmapsto \sf \frac{3}{7}- \frac{6}{13}- \frac{8}{21}+ \frac{5}{21}$

$\longmapsto \sf \frac{117 - 126 - 104 + 65}{273}$

$\longmapsto \sf - \frac{48}{273}$

$\longmapsto \sf \frac{16}{91}$
