Ответ:
- а) \(−0.56+(3.8−2.44)=−0.56+1.36=0.8\).
- б) \(−3.24−(−4.76−2.9)=−3.24−(−7.66)=4.42\).
- в) \(2\frac{7}{15}−(2\frac{2}{15}−8\frac{1}{9})=\frac{37}{15}−\left(\frac{32}{15}−\frac{73}{9}\right)=\frac{37}{15}−\frac{32}{15}+\frac{73}{9}=\frac{76}{9}=8\frac{4}{9}\).
Ответ: а) 0,8; б) 4,42; в) 8 4/9.
