[tex] \frac{5}{6} x \div 1 \frac{1}{2} = 0.25 \\ \frac{5}{6} x = \frac{25}{100} \times \frac{3}{2} \\ \frac{5}{6} x = \frac{75}{200} \\ x = \frac{75}{200} \div \frac{5}{6} \\ x = \frac{75}{200} \times \frac{6}{5} \\ x = \frac{450}{1000} = 0.45[/tex]
5/6x : 1 1/2 = 0,25
5/6x : 3/2 = 0,25
5/6x * 2/3 = 0,25
5/3x * 1/3 = 0,25
5/9x = 0,25
x = 9/5 * 0,25
x = 9/5 * 1/4
x = 9/20
x = 0,45


1 intreg 1/2 = ( 1*2+1)/2 = (2+1)/2 = 3/2
