a)\(\frac{18}{-5}.\frac{-5}{6}=\frac{18}{6}=3\)
c)\(\frac{115}{30}\div\frac{-5}{6}=\frac{115}{30}.\frac{6}{-5}=\frac{-23}{5}\)
d)\(-3x+\frac{1}{2}=3\)
\(-3x=3-\frac{1}{2}\)
\(-3x=\frac{5}{2}\)
\(x=\frac{5}{2}\div3\)
\(x=\frac{5}{6}\)

a)= 18/-5 . -5/6 , bỏ -5=3
c)= 115/30 : 5/6 = 23/6 :5/6 =23/6 . 6/5 bỏ 6 = 23/5
d) 3.x +1/2 = 3:
3.x = 3-1/2 =5/2
x =5/2 : 3 = 5/6
