"pi" is just another number. Fractions that contain the number pi can be dealt with like all other fractions.
Examples:
Example 1...
[tex]\frac { 1 }{ \pi } +\frac { 1 }{ \pi } =\frac { 1+1 }{ \pi } =\frac { 2 }{ \pi }[/tex]
Example 2...
[tex]\\ \\ \frac { \pi }{ 3 } +\frac { 2\pi }{ 3 } =\frac { \pi +2\pi }{ 3 } =\frac { 3\pi }{ 3 } =\pi [/tex]
Example 3...
[tex]\\ \\ \frac { 2 }{ 3\pi } +\frac { 5 }{ 4\pi } \\ \\ =\frac { 2 }{ 3\pi } \cdot \frac { 4 }{ 4 } +\frac { 5 }{ 4\pi } \cdot \frac { 3 }{ 3 } \\ \\ =\frac { 8 }{ 12\pi } +\frac { 15 }{ 12\pi } \\ \\ =\frac { 8+15 }{ 12\pi } \\ \\ =\frac { 23 }{ 12\pi } [/tex]
