Ответ:
а) \(4.3-2\frac{1}{15}=\frac{43}{10}-\frac{31}{15}=\frac{129-62}{30}=\frac{67}{30}=2\frac{7}{30}\).
б) \(\frac{5}{6}+2.25=\frac{5}{6}+\frac{9}{4}=\frac{10+27}{12}=\frac{37}{12}=3\frac{1}{12}\).
в) \(1.3\cdot4\frac{1}{6}=\frac{13}{10}\cdot\frac{25}{6}=\frac{65}{12}=5\frac{5}{12}\).
г) \(\frac{5}{16}:0.125=\frac{5}{16}:\frac{1}{8}=\frac{5}{2}=2\frac{1}{2}\).
Ответ: а) \(2\frac{7}{30}\); б) \(3\frac{1}{12}\); в) \(5\frac{5}{12}\); г) \(2\frac{1}{2}\).
