87 = 3*29 91 = 7*13 106= 2*53 143=13*11
159 = 3*53 205 = 5*41
[tex]\frac{34}{82} = \frac{2*17}{2*41} = \frac{17}{41}[/tex]
[tex]\frac{58}{87} = \frac{2*29}{3*29} = \frac{2}{3}[/tex]
[tex]\frac{82}{58}=\frac{2*41}{2*29} =\frac{41}{29}[/tex]
[tex]\frac{34}{85}=\frac{2*17}{5*17}=\frac{2}{5}[/tex]
[tex]\frac{91}{143}=\frac{7*13}{13*11} = \frac{7}{13}[/tex]
