a) 1 : 3
1 = [tex]\frac{1}{1}[/tex]
3 = [tex]\frac{3}{1}[/tex]
[tex]\frac{1}{1} : \frac{3}{1} = \frac{1}{1} * \frac{1}{3} =\frac{1}{3}[/tex]
[tex]1 : \frac{1}{3} \\\\1 = \frac{1}{1}\\\\\frac{1}{1} : \frac{1}{3} =\frac{1}{1} * \frac{3}{1} = \frac{3}{1}[/tex]
[tex]1 : \frac{4}{8} \\\\1 = \frac{1}{1} \\\\\frac{1}{1} : \frac{4}{8} = \frac{1}{1} *\frac{8}{4} = \frac{8}{4} = \frac{2}{1}[/tex]
b)
[tex]3 : 1 \\\\3 = \frac{3}{1}\\\\1 = \frac{1}{1} \\\\\frac{3}{1} : \frac{1}{1} = \frac{3}{1} * \frac{1}{1} = \frac{3}{1}[/tex]
