a.

[tex]1 = \frac{12}{12}[/tex]

[tex]\frac{12}{12} < \frac{17}{12}[/tex][/tex]

b.

[tex]\frac{ - 5}{6} = \frac{ - 5 \times 5}{6 \times 5} = \frac{ - 25}{25}[/tex]

[tex]\frac{8}{5} = \frac{8 \times 6}{5 \times 6} = \frac{48}{25}[/tex]

[tex]\frac{ - 25}{25} < \frac{48}{25}[/tex]

c.

[tex]\frac{ - 3}{7} = \frac{ - 3 \times 14}{7 \times 14} = \frac{ - 42}{98}[/tex]

[tex] \frac{ - 5}{14} = \frac{ - 5 \times 7}{14 \times 7} = \frac{ - 35}{98} [/tex]

[tex] \frac{ - 42}{98} < \frac{ - 35}{98} [/tex]
