## Algebra 2 Common Core

Because the denominators are 3 and 4 and we need a common denominator, we can use 12 as the common denominator because it is the Least Common Multiple of 3 and 4. Now we have $-2\frac{4}{12}$+$3\frac{3}{12}$. We can add the whole numbers and the fraction parts separately to get $1+ -\frac{1}{12} = \frac{11}{12}$
