Show how to solve 5 3/4+ 1 2/3 in two different ways. In each case, express your answer as a mixed number. Explain why both of the methods are legitimate.
Thank you
The numbers above are fractiones
The OP meant simplify.
In this case....
$\displaystyle 5 \frac{3}{4} + 1 \frac{2}{3}$
Simplifies to:
$\displaystyle \frac{20+3}{4} + \frac{3+2}{3}$
$\displaystyle \frac{23}{4} + \frac{5}{3}$
LCD is 12
$\displaystyle \frac{69}{12} + \frac{20}{12}$
$\displaystyle \frac{89}{12}$
$\displaystyle 7 \frac{5}{12}$
Another way to do this is to find the LCD when they are mixed numbers, and then simplify them to normal fractions.
