Add the fractions and simplify the answer 1/2 +2 /3

What we are going to do is add $\frac{1}{2}$ by $\frac{2}{3}$ . The first thing we do is make common denominators for $\frac{1}{2}$ and $\frac{2}{3}$ : $\frac{1*3}{2*3}= \frac{3}{6} \ and \ \frac{2*2}{3*2}= \frac{4}{6}$ . Now we add $\frac{3}{6}$ by $\frac{4}{6}$ : $\frac{3}{6}+ \frac{4}{6}= \frac{7}{6}$ . Now we make $\frac{7}{6}$ a mixed number: $\frac{7}{6}=1 \frac{1}{6}$ . Therefore, your answer is $\boxed{\boxed{1 \frac{1}{6}}}$ . Hoped I helped. :)
