Answer 2

Answer:

$\frac{-389}{168}$

Step-by-step explanation:

$\frac{-3}{4}+ \frac{-5}{14}+ \frac{5}{-6}+ \frac{-3}{8}$

LCM = 168

Convert the denominator to 168.

$=\frac{-126}{168}+ \frac{-60}{168}+ \frac{-140}{168}+ \frac{-63}{168}$

=$\frac{(-126)+(-60)+(-140)+(-63)}{168}$

$=\frac{(-186)+(-203)}{168}$

$=\frac{-389}{168}$    (Decimal: -2.315476)
