Hello Dear User__________

Here is Your Answer...!!

Step by step solution:

a.

$Given \ (\frac{-5}{16})+(-\frac{7}{5})\\\\we \ have \ to \ solve \ it.\\\\Let \ us \ do\\\\ (\frac{-5}{16})+(-\frac{7}{5})\\\\\frac{-5-112}{80}\\\\\frac{-137}{80}$

b.

$Given \ (\frac{-4}{5})+(-\frac{12}{25})\\\\we \ have \ to \ solve \ it.\\\\Let \ us \ do\\\\ (\frac{-4}{15})+(-\frac{12}{25})\\\\\frac{-20-12}{75}\\\\\frac{-32}{25}$

c.

$Now \ we \ have \ to \ solve \ (\frac{6}{21})-(-\frac{10}{27})\\\\Let \ us \ do\\\\(\frac{6}{21})-(-\frac{10}{27})=\frac{54+70}{189}=\frac{124}{189}$

d.

$(\frac{-16}{25})\times(-\frac{35}{32})\\\\\frac{-1}{5}\times-\frac{7}{2}\\\\\frac{7}{10}$

e.

$(\frac{-4}{7})/(\frac{36}{21})\\\\(\frac{-4}{7})\times(\frac{21}{36})\\\\(\frac{-1}{1})\times(\frac{3}{9})\\\\\frac{-1}{3}$

f.

$(\frac{-15}{14})/(\frac{16}{7})\\\\(\frac{-15}{14})\times\frac{7}{16}\\\\\frac{-15}{2}\times\frac{1}{16}\\\\\frac{-15}{32}$

Hope it is clear to you.
