Answer 2

Answer:

$\frac{-40}{231}$

Step-by-step explanation:

The Given Equation:     $\frac{3}{7}$ + $\frac{-6}{11}$ + $\frac{-8}{21}$+ $\frac{5}{22}$

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

= $\frac{((\frac{462}{7})*3)+((\frac{462}{11} )*(-6))+((\frac{462}{21} )*(-8))+((\frac{462}{22})*5) }{462}$

= $\frac{(66*3)+(42*(-6))+(22*(-8))+(21*5)}{462}$

= $\frac{198 + (-252) + (-176) + 105}{462}$

= $\frac{198-252-176+105}{462}$

= $\frac{-80}{462}$

= $\frac{(-80)/2}{(462)/2}$

= $\frac{-40}{231}$

= -0.1731601732...

≈ -0.17

Hope you understand the proccess...
