<var>A)\frac{\frac{1}{0,32}}{-1,6}\\\\\frac{\frac{100}{32}}{\frac{-16}{10}}=\frac{100}{32}*\frac{-10}{16}=\frac{-1000}{512}\\\\\frac{-125}{64}</var>

 

<var>B)(-42,723)-(814,9)=857,623</var>

 

<var>C)(-3,7)(-2,4)(-1,1)(-0,5)\\\\\frac{-37}{10}*\frac{-24}{10}*\frac{-11}{10}*\frac{-1}{2}=\ \frac{9768}{2000}\\\\\frac{1221}{250}</var>

 

<var>D)\frac{1}{0,125}+\frac{1}{6}\\\\\frac{1000}{125}+\frac{1}{6}=\frac{6000+125}{750}=\frac{6125}{750}\\\\\frac{49}{6}</var><var>D)\frac{1}{0,125}+\frac{1}{6}\\\\\frac{1000}{125}+\frac{1}{6}=\frac{6000+125}{750}=\frac{6125}{750}\\\\\frac{49}{6}</var>
