Answer 2

Answer:

$\frac{ - 381}{88}$

Step-by-step explanation:

$\frac{3}{8} + ( \frac{ - 5}{11} ) + ( \frac{ - 21}{8} ) + ( \frac{ - 13}{8} )$

After rearranging the problem(commutative property),

$= \frac{3}{8} + ( \frac{ - 21}{8} ) + ( \frac{ - 13}{8}) + ( \frac{ - 5}{11} )$

$= \frac{3}{8} - \frac{21}{8} - \frac{13}{8} - \frac{5}{11}$

Using associative property,

$( \frac{3}{8} - \frac{21}{8} - \frac{13}{8} ) - \frac{5}{11}$

$= ( \frac{3 - 21 - 13}{8} ) - \frac{5}{11}$

$= \frac{ - 31}{8} - \frac{5}{11}$

Now, by taking common denominator,

$\frac{ - 341}{88} - \frac{40}{88}$

$= \frac{ - 341 - 40}{88}$

$= \frac{ - 381}{88}$
