Answer 1

Hyy Dude ✿●‿●✿

Solution :-

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

Taking L.C.M. of the denominators 7, 11, 21 and 22 and then solving it.

L.C.M. of 7, 11, 21 and 22 = 2*3*7*11

L.C.M. of 7, 11, 21 and 22 = 2*3*7*11= 462

= (462/7)*3 - (462/11)*6 - (462/21)*8 + (462/22)*5

= (198/462) - (252/462) - (176/462) + (105/462)

= (303/462) - (428/462)

= (-125/462)

Answer 2

Answer:

$\frac{-125}{462}$

Step-by-step explanation:

$\frac{3}{7} + \frac{-6}{11} + \frac{-8}{21} + \frac{5}{22}$

Regrouping,

= $\frac{3}{7} + \frac{-8}{21} + \frac{-6}{11} + \frac{5}{22}$

= $\frac{9 - 8}{21} + \frac{-12 + 5}{22}$

= $\frac{1}{21} + \frac{-7}{22}$

= $\frac{22 - 147}{462}$

= $\frac{-125}{462}$
