Question

Tìm x:

\(\dfrac{x}{\text{2,7}}\)=\(\dfrac{\text{-2}}{\text{3,6}}\)

giúp mình với

Answer 1

\(\dfrac{x}{2,7}=\dfrac{-2}{3,6}\)

=> x.3,6 = -2.2,7

x.3,6 = -5,4

x = -5,4 : 3,6

x = -1,5

Vậy x = -1,5

Answer 2

\(\dfrac{x}{2,7}=\dfrac{-2}{3,6}\)

\(\Leftrightarrow x.3,6=-2.2,7\)

x.3,6=-5,4

x=-5,4:3,6

x=-1,5

Answer 3

\(\dfrac{x}{2,7}=\dfrac{-2}{3,6}\)

\(\Leftrightarrow x.3,6=-2.2,7\)

\(\Leftrightarrow x.3,6=-5,4\)

\(\Leftrightarrow x=-1,5\)

Answer 4

Ta có: \(\dfrac{x}{2,7}=\dfrac{-2}{3,6}\)

\(\Rightarrow x\times3,6=-2\times2,7\)

\(\Rightarrow x\times3,6=-5,4\)

\(\Rightarrow x=-5,4\div3,6\)

\(\Rightarrow x=-1,5\)

Vậy \(x=-1,5\)
