(2,5 - 3x) : 1/4 = 5/3
=> 2,5 - 3x = 5/3 . 1/4
=> 2,5 - 3x = 5/12
=> 3x = 2,5 - 5/12
=> 3x = 25/12
=> x = 25/12 : 3
=> x = 25/36
\(\left(2,5-3x\right):\frac{1}{4}=\frac{5}{3}\)
\(2,5-3x=\frac{5}{3}.\frac{1}{4}\)
\(2,5-3x=\frac{5}{12}\)
\(3x=2,5-\frac{5}{12}=\frac{25}{12}\)
\(x=\frac{25}{12}:3=\frac{25}{36}\)
\(\left(2,5-3x\right)\):\(\frac{1}{4}=\frac{5}{3}\)
\(\left(\frac{25}{10}-3x\right)\)=\(\frac{5}{3}\cdot\frac{1}{4}\)
\(3x=\frac{25}{10}-\frac{5}{12}\)
\(3x=\frac{25}{12}\)
\(x=\frac{25}{12}:3\)
\(x=\frac{25}{36}\)
