Answer 1

$4\frac{1}{3} +8\frac{4}{6}=\frac{13}{3}+ \frac{52}{6}=\frac{13*2+52}{6}=\frac{78}{6} =13\\9\frac{1}{5} +15\frac{9}{25}=\frac{46}{5}+ \frac{384}{25}=\frac{46*5+384}{25} = \frac{614}{25}=24\frac{14}{25} \\11\frac{1}{6}+2 \frac{3}{4}=\frac{67}{6} +\frac{11}{4}=\frac{67*2+11*3}{12}=\frac{167}{12}= 13\frac{11}{12}$
