<s>[INST] What am I doing wrong with this adding fractions problem: $\frac{5}{6} + \frac{2}{3}$? 
The problem is $$\frac{5}{6} + \frac{2}{3}$$ 

I found the LCD which is $6$. Then I multiplied $2\times 3=6$ and $2\times 2=4$. So the new problem is 
$$\frac{5}{6} + \frac{4}{6} = \frac{11}{6}$$
$\frac{11}{6}$ simplified is $1 \frac{5}{6}$ but that's not an answer I can select. 
 [/INST] As Kenny Lau so thoughtfully pointed out, $5+4=9$.
$$\frac{5}{6}+\frac{2}{3}=\frac{5}{6}+\frac{4}{6}=\frac{9}{6}=\frac{3}{2}$$
