3/5*x=2/3-2/7

Answer 1

    \(18,2:x=1,4\times4\)

\(\Rightarrow18,2:x=5,6\)

\(\Rightarrow x=3,25\)

    \(\frac{3}{5}\times x=\frac{2}{3}-\frac{2}{7}\)

\(\Rightarrow\frac{3}{5}\times x=\frac{8}{21}\)

\(\Rightarrow x=\frac{40}{63}\)

Answer 2

18,2 : x =1,4 x 4

18,2 : x =5,6

x = 18,2 ; 5,6

x = 3,25

Answer 3

\(18,2:x=1,4\cdot4\)

             \(x=5,6\)

             \(x=18,2:5,6\)

             \(x=3,25\)   

\(\frac{3}{5}\cdot x=\frac{2}{3}-\frac{2}{7}\)

         \(x=\frac{8}{21}\)

         \(x=\frac{8}{21}:\frac{3}{5}\)

         \(x=\frac{40}{63}\)
