1. a) \(\frac{4}{5}-\frac{1}{2}=\frac{8}{10}-\frac{5}{10}=\frac{3}{10}\).
2. b) \(\frac{7}{8}-\frac{3}{5}=\frac{35}{40}-\frac{24}{40}=\frac{11}{40}\).
3. c) \(\frac{7}{9}-\frac{3}{4}=\frac{28}{36}-\frac{27}{36}=\frac{1}{36}\).
4. d) \(4-\frac{1}{3}=\frac{12}{3}-\frac{1}{3}=\frac{11}{3}=3\frac{2}{3}\).
