a)
[tex]0,5 \cdot \frac{1}{2} = \frac{1}{2} \cdot \frac{1}{2} =\frac{1}{4} = 0,25 \\\\ 0,125 \cdot 4 = \frac{125}{1000} \cdot \frac{4}{1} = \frac{5}{10} =\frac{1}{2} = 0,5[/tex]
b)
[tex]\frac{1}{2} : 0,5 = \frac{1}{2} \cdot 2 = 1 \\\\ 0,75 : 4 = \frac{3}{4} : 4 = \frac{3}{4} \cdot \frac{1}{4} = \frac{3}{16} = 0,1875[/tex]
c)
[tex]\frac{7}{2} \cdot 0,25 = \frac{7}{2} \cdot \frac{1}{4} = \frac{7}{8} = 0,875 \\\\ 0,375 :2 = \frac{375}{1000} \cdot \frac{1}{2} =\frac{375}{2000} = \frac{15}{80} = \frac{3}{16} = 0,1875[/tex]
