Answer 1

$1)3\frac{7}{9}+5\frac{1}{6}=(3+5)+(\frac{7}{9}+\frac{1}{6})=8+\frac{7\times2+1\times3}{18}=8+\frac{14+3}{18}=8+\frac{17}{18}=8\frac{17}{18}$

$2)8\frac{7}{16}+3\frac{3}{10}=(8+3)+(\frac{7}{16}+\frac{3}{10})=11+\frac{7\times5+3\times8}{80}=11+\frac{35+24}{80}=11+\frac{59}{80}=11\frac{59}{80}$

$3)6\frac{8}{12}+9\frac{7}{18}=(6+9)+(\frac{8}{12}+\frac{7}{18})=15+(\frac{2}{3}+\frac{7}{18})=15+\frac{2\times6+7}{18}=15+\frac{12+7}{18}=15+\frac{19}{18}=15+1\frac{1}{18}=16\frac{1}{18}$

$4)9\frac{3}{16}+4\frac{7}{12}+3\frac{5}{24}=(9+4+3)+(\frac{3}{16}+\frac{7}{12}+\frac{5}{24})=16+\frac{3\times3+7\times4+5\times2}{48}=16+\frac{9+28+10}{48}=16+\frac{47}{48}=16\frac{47}{48}$
