Ответ:
- \(−1\frac{1}{5}\cdot(−15)=\frac{−6}{5}\cdot(−15)=18\).
- \(−1.95−8.68=−10.63\).
- \(−7−(−4)+3=−7+4+3=0\).
- \(−2.16:\frac{103}{20}=−\frac{54}{25}\cdot\frac{20}{103}=−\frac{216}{515}\).
- \(1\frac{1}{8}−3\frac{5}{6}=\frac{9}{8}−\frac{23}{6}=\frac{27−92}{24}=−\frac{65}{24}=−2\frac{17}{24}\).
Ответ: 18; −10,63; 0; \(−\frac{216}{515}\); \(−2\frac{17}{24}\).
