a. 5/3 : x/4 = 6 : 0.3

Answer 1

\(\frac{5}{3}:\frac{x}{4}=6:0,3\)

\(\frac{20}{3x}=20\)

\(3x=1\)

  \(x=\frac{1}{3}\)

Vậy \(x=\frac{1}{3}\)

Answer 2

\(\frac{5}{3}\div\frac{x}{4}=6\div0,3\)

\(\Rightarrow\frac{5}{3}\div\frac{x}{4}=20\)

\(\Rightarrow\frac{x}{4}=\frac{1}{12}\)

\(\Rightarrow\frac{3x}{12}=\frac{1}{12}\)

\(\Rightarrow3x=1\)
