Question

vì sao 2 số này = nhau ạ

Answer 1

\(Tacó:\dfrac{2x}{3}=\dfrac{x}{\dfrac{3}{2}}\Rightarrow\dfrac{2x}{x}=\dfrac{3}{\dfrac{3}{2}}\\ x=2\)

Answer 2

\(\dfrac{2x}{3}=\dfrac{x}{\dfrac{3}{2}}\\ \Rightarrow\dfrac{3}{2}\times2x=3x\\ \Rightarrow\dfrac{6x}{2}=3x\\ \Rightarrow3x=3x\)

\(\Rightarrow\dfrac{2x}{3}=\dfrac{x}{\dfrac{3}{2}}\)

Answer 3

\(\dfrac{2x}{3}=\dfrac{x}{\dfrac{3}{2}}\)

\(\Rightarrow2x.\dfrac{3}{2}=3.x\)

\(\Rightarrow x.3=3.x\left(luon-dung\right)\)

Answer 4

\(\dfrac{2\text{x}}{3}=\dfrac{x}{\dfrac{3}{2}}\)

\(\Leftrightarrow\dfrac{2\text{x}}{3}=\dfrac{x}{3}:\dfrac{1}{2}\)

\(\Leftrightarrow\dfrac{2\text{x}}{3}=\dfrac{x}{3}\times2\)

\(\Leftrightarrow\dfrac{2\text{x}}{3}=\dfrac{2\text{x}}{3}\)
