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) \(1,3:1\frac{1}{6}=\frac{13}{10}:\frac{7}{6}=\frac{13}{10}\cdot\frac{6}{7}=\frac{39}{35}=1\frac{4}{35}\).
г) \(\frac{5}{16}:0,125=\frac{5}{16}:\frac{1}{8}=\frac{5}{16}\cdot8=\frac{5}{2}=2,5\).
Ответ: а) \(2\frac{7}{30}\); б) \(3\frac{1}{12}\); в) \(1\frac{4}{35}\); г) \(2,5\).
