Answer 1

$a)5\frac{5}{6}+3\frac{2}{9}=(5+3)+(\frac{5}{6}+\frac{2}{9})=8+\frac{19}{18}=8+1\frac{1}{18}=8+1+\frac{1}{18}=9+\frac{1}{18}=9\frac{1}{18}=9,05\\b)1\frac{1}{5}+2\frac{2}{9}=(1+2)+(\frac{1}{5}+\frac{2}{9})=3+\frac{19}{45}=3\frac{19}{45}=3,42\\c)7\frac{5}{8}-2\frac{1}{6}=(7-2)+(\frac{5}{8}-\frac{1}{6})=5+\frac{11}{24}=5\frac{11}{24}\\d)2\frac{1}{2}-1\frac{3}{8}=(2-1)+(\frac{1}{2}-\frac{3}{8})=1+\frac{1}{8}=1\frac{1}{8}=1,125$
