Add the fractions and simplify the answer 1/2 +2 /3
IrinaVladis [17]
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. :)
