me ajude,por favor.URGENTE!!!!!!!!!

 

a)   1  /  0,32      :    (-1,6) =

     

b)  (-42,723) - (+814,9)=

 

c) (-3,7) . (-2,4) ( -1,1) . (-0,5)=

 

d) 1 / 0,125 + 1/6=

Answer 1

a) 3,25 :(-1,6)=-1,953125

 

 

b)  (-42,723) - (+814,9)=-857,623

 

 

c)  (-3,7) . (-2,4) ( -1,1) . (-0,5)=4,884

 

d)  1 / 0,125 + 1/6=8+1/6=14/6=7/3

Answer 2

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

 

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

 

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

 

$<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>$
