[tex]\frac{3}{7^{2}} = \frac{3}{21} = \frac{1}{7}[/tex]
[tex]\frac{2}{5^{2}} = \frac{2}{25}[/tex]
[tex]\frac{8}{7^{2}} = \frac{8}{49}[/tex]
[tex]1\frac{1}{8^{2}} = 1\frac{1}{64}[/tex]
[tex]\frac{1}{2^{3}} = \frac{1}{8}[/tex]
[tex]\frac{2}{3^{3}} = \frac{2}{27}[/tex]
[tex]2\frac{1}{2^{3}} = 2\frac{1}{8}[/tex]
[tex]1\frac{1}{4^{3}} = 1\frac{1}{64}[/tex]
