Ответ:
а) \(0{,}62-\frac{3}{8}=\frac{31}{50}-\frac{3}{8}=\frac{124}{200}-\frac{75}{200}=\frac{49}{200}\).
б) \(0{,}48+\frac{1}{3}=\frac{12}{25}+\frac{1}{3}=\frac{36}{75}+\frac{25}{75}=\frac{61}{75}\).
в) \(\frac{11}{15}+0{,}4-\frac{8}{15}=\frac{3}{15}+\frac{2}{5}=\frac{1}{5}+\frac{2}{5}=\frac{3}{5}\).
Ответ: а) \(\frac{49}{200}\); б) \(\frac{61}{75}\); в) \(\frac{3}{5}\).
