The OP meant simplify.

In this case....

5 \frac{3}{4} + 1 \frac{2}{3}

Simplifies to:

\frac{20+3}{4} + \frac{3+2}{3}

\frac{23}{4} + \frac{5}{3}

LCD is 12

\frac{69}{12} + \frac{20}{12}

\frac{89}{12}

7 \frac{5}{12}

Another way to do this is to find the LCD when they are mixed numbers, and then simplify them to normal fractions.
