0,66666=2/3
0,16666=1/6
2,5=5/2
0,25=1/4
0,5=1/2


\frac{(\frac{2x}{3}+\frac{1}{6})}{\frac{5x}{2}-\frac{1}{4}}=\frac{1}{2}

(\frac{2x}{3}+\frac{1}{6})=(\frac{1}{2})(\frac{5x}{2}-\frac{1}{4})

\frac{2x}{3}+\frac{1}{6}=\frac{5x}{4}-\frac{1}{8}

\frac{16x}{24}+\frac{4}{24}=\frac{30x}{24}-\frac{3}{24}


16x+4=30x-3

4+3=30x-16x

7=14x

x=1/2
