Question

x+60%x=1/5

 

Answer 1

\(x+60\%x=\dfrac{1}{5}\\ \Rightarrow x+0,6x=0,2\\ \Rightarrow1,6x=0,2\\ \Rightarrow x=0,125\)

Answer 2

\(x+\dfrac{3}{5}x=\dfrac{1}{5}\)

\(x\times\left(1+\dfrac{3}{5}\right)=\dfrac{1}{5}\)

\(x\times\dfrac{8}{5}=\dfrac{1}{5}\)

\(x=\dfrac{1}{5}:\dfrac{8}{5}\)

\(x=\dfrac{1}{8}\)
