Ответ:

  1. \(\frac{8}{25}-0,2=0,32-0,2=0,12\).
  2. \(0,7+\frac{1}{5}=0,7+0,2=0,9\).
  3. \(\frac{3}{20}+0,15=0,15+0,15=0,3\).
  4. \(0,9-\frac{3}{5}=0,9-0,6=0,3\).
  5. \(\frac{3}{4}-0,15=0,75-0,15=0,6\).
  6. \(\frac{19}{50}+0,02=0,38+0,02=0,4\).
  7. \(\frac{7}{50}+0,6=0,14+0,6=0,74\).
  8. \(0,5-\frac{11}{25}=0,5-0,44=0,06\).
  9. \(\frac{5}{6}-\frac{22}{27}=\frac{45}{54}-\frac{44}{54}=\frac{1}{54}\).
  10. \(\frac{7}{12}+\frac{3}{20}=\frac{35}{60}+\frac{9}{60}=\frac{44}{60}=\frac{11}{15}\).
