a) x/27=-2/3.6
Ta có: x.3,6=27.(-2)
<=>x.3,6=-54
<=>x=-54/3,6
<=>x=-15
Vậy x =-15
b) -0,52 : x = -9,36: 16,38
Ta có: -0,52/x=-4/7
<=>x=0.91
Vậy x=0.91
a) \(\dfrac{x}{27}=\dfrac{-2}{3,6}\) <=> \(x=\dfrac{27.\left(-2\right)}{3,6}\) <=> \(x=-15\) Vậy \(x=-15\) b) \(-0,52:x=-9,36:16,38\) \(-0,52:x=\dfrac{-4}{7}\) \(x=\dfrac{91}{100}\) Vậy \(x=\dfrac{91}{100}=0,91\)
