For this case we have the following expression:
[tex]\frac {1} {2} + \frac {1} {4}[/tex]
So, we have:
[tex]\frac {1} {2} + \frac {1} {4} = \frac {4 * 1 + 2 * 1} {2 * 4} = \frac {4 + 2} {8} = \frac {6 } {8}[/tex]
Simplifying we have to finally:
[tex]\frac {6} {8} = \frac {3} {4}[/tex]
ANswer:
[tex]\frac {3} {4}[/tex]
