Question

find the value of 3/7+(-6/11)+(-8/21)+5/22

Answer 1

Hey friend,
Here is the answer you were looking for:
$\frac{3}{7} - \frac{6}{11} - \frac{8}{21} + \frac{5}{22 } \\ \\ = taking \: lcm \: we \: get \: \\ \\ = \frac{3 \times 66 - 6 \times 42 - 8 \times 22 + 5 \times 21}{462} \\ \\ = \frac{198 - 252 - 176 + 105}{462} \\ \\ = \frac{303 - 423}{462} \\ \\ \frac{ - 125}{462}$

Hope this helps!!

Answer 2

sorry for late answering,

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

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

3/7 - 8/21 + 5/22 -6/11 

_____________________________________________________


solving in two parts,

3/7 - 8/21          ------1 part 

taking LCM,

= (9-8)/21

= 1/21

________________________________________________

second part , 5/22 - 6/11 

 = (5- 12)/22

=  -7/22 
___________________________________________

Now,

-7/22 + 1/21 

= 1/21  - 7/22 

= taking LCM, [ LCM = 21 *22 =462] 

Now,

(22 -147 )/462

=  -125/462 




 i hope this will help you
