Answer 1

1)$8\frac{3}{7}-4\frac{2}{5} =\frac{59}{7} -\frac{22}{5}= \frac{141}{35}=4\frac{1}{35} \\6\frac{11}{15}-2\frac{7}{10}=\frac{101}{15}-\frac{27}{10}=\frac{121}{30}=4\frac{1}{30} \\16\frac{17}{18}-2\frac{11}{12} =\frac{305}{18}-\frac{35}{12} =\frac{505}{36}=14\frac{1}{36} \\18\frac{13}{48} -5\frac{3}{64} = \frac{877}{48} -\frac{323}{64}=\frac{2539}{192}=13\frac{43}{192}$

2)$3\frac{7}{9} +5\frac{1}{6}=\frac{34}{9} +\frac{31}{6} =\frac{161}{18} =8\frac{17}{18}$

   $8\frac{7}{16}+3\frac{3}{10} =\frac{135}{16}+\frac{33}{10}=\frac{939}{80}=11\frac{59}{80}$
