Answer 1

$6\frac{7}{13} +4\frac{5}{22} =(6+4)+(\frac{7}{13}+\frac{5}{22})=10+\frac{154+65}{286} =10\frac{219}{286}$

$13\frac{5}{6} +21\frac{7}{24}=(13+21)+(\frac{5}{6}+\frac{7}{24})=34+\frac{20+7}{24}=35\frac{3}{24}=35\frac{1}{8}$

$31+32\frac{5}{14} =31+32+\frac{5}{14}= 63\frac{5}{14}$

$312\frac{2}{5} +16\frac{4}{15}=(312+16)+(\frac{2}{5}+\frac{4}{15})=328+\frac{6+4}{15}=328\frac{10}{15}=328\frac{2}{3}$

$23\frac{1}{9}+13\frac{6}{21}=(23+13)+(\frac{1}{9}+\frac{6}{21})=36+\frac{7+18}{63} =36\frac{25}{63}$

$32+10\frac{6}{13}=32+10+\frac{6}{13} =42\frac{6}{13}$

$4\frac{5}{9}+1627=4+1627+\frac{5}{9} =1631\frac{5}{9}$
