Answer 1

Answer:

-61/168 = -0.36

Step-by-step explanation:

$(\frac{2}{11} *\frac{-22}{15} )+(\frac{-1}{6} *\frac{3}{4} )+(\frac{-1}{21} *\frac{-3}{5} )\\\\(\frac{2}{1} *\frac{-2}{15})+(\frac{-1}{2} *\frac{1}{4})+(\frac{-1}{7} *\frac{-1}{5})\\\\\frac{-4}{15} +(\frac{-1}{8} )+\frac{1}{35} \\\\\frac{-4}{15} -\frac{1}{8} +\frac{1}{35} \\\\Taking LCM,\\\\\frac{56(-4)-105(1)+24(1)}{840} \\\\\frac{-224-105+24}{840} \\\\\frac{-329+24}{840} \\\\\frac{-305}{840} \\\\\frac{-61}{168} \\\\-0.36$
