For this case we must find the value of the following expression:
[tex]5 \frac {3} {4} +2 \frac {3} {4}[/tex]
We have to:
[tex]5 \frac {3} {4} = \frac {4 * 5 + 3} {4} = \frac {20 + 3} {4} = \frac {23} {4}\\2 \frac {3} {4} = \frac {4 * 2 + 3} {4} = \frac {8 + 3} {4} = \frac {11} {4}[/tex]
Rewriting the expression we have:
[tex]\frac {23} {4} + \frac {11} {4} = \frac {23 + 11} {4} = \frac {34} {4} = \frac {17} {2}[/tex]
Answer:
[tex]\frac {17} {2} = 8 \frac {1} {2}[/tex]
