Answer 1

$1. 3 \frac{3}{12}+ \frac{5}{12}=3 \frac{3+5}{12}=3 \frac{8}{12}=3 \frac{2}{3}.$
$2. 3 \frac{3}{12}+1 \frac{5}{12}=4 \frac{3+5}{12}= 4\frac{8}{12}=4 \frac{2}{3}.$
$3. 3 \frac{3}{12}+ \frac{11}{12}=3 \frac{3+11}{12}=3 \frac{14}{12}=4 \frac{2}{12}=4 \frac{1}{6}.$
$4. 3 \frac{3}{12}+1 \frac{11}{12}=4 \frac{3+11}{12}=4 \frac{14}{12}=5 \frac{2}{12}=5 \frac{1}{6}.$
