  1. в) \(5+\frac{1}{3}=5\frac{1}{3}\).

  2. г) \(5-\frac{1}{3}=4\frac{3}{3}-\frac{1}{3}=4+\frac{2}{3}=4\frac{2}{3}\).

  3. д) \(7\frac{5}{8}+3\frac{1}{8}=10+\left(\frac{5}{8}+\frac{1}{8}\right)=10\frac{6}{8}=10\frac{3}{4}\).

  4. е) \(5\frac{3}{10}+2\frac{1}{5}=5\frac{3}{10}+2\frac{2}{10}=7+\left(\frac{3}{10}+\frac{2}{10}\right)=7\frac{5}{10}=7\frac{1}{2}\).

  5. ж) \(5\frac{3}{10}-2\frac{1}{5}=5\frac{3}{10}-2\frac{2}{10}=3+\left(\frac{3}{10}-\frac{2}{10}\right)=3\frac{1}{10}\).

  6. з) \(3\frac{1}{2}-1\frac{3}{4}=3\frac{2}{4}-1\frac{3}{4}=2\frac{6}{4}-1\frac{3}{4}=1\frac{3}{4}\).
