Ответ:
Решение:
- \(4\frac{5}{14}-7\frac{11}{14}+4\frac{13}{14}=\frac{61-109+69}{14}=\frac{21}{14}=1\frac{1}{2}\).
- \(10\frac{11}{25}+7\frac{14}{25}-6\frac{12}{25}=\frac{261+189-162}{25}=\frac{288}{25}=11\frac{13}{25}\).
- \(10\frac{4}{31}-\left(6\frac{8}{31}+3\frac{4}{31}\right)=\frac{314-(194+97)}{31}=\frac{23}{31}\).
- \(8\frac{4}{15}-6\frac{13}{15}+7\frac{14}{15}=\frac{124-103+119}{15}=\frac{140}{15}=9\frac{1}{3}\).
- \(6\frac{5}{24}+9\frac{19}{24}-5\frac{13}{24}=\frac{149+235-133}{24}=\frac{251}{24}=10\frac{11}{24}\).
- \(12\frac{4}{29}-\left(7\frac{7}{29}+4\frac{4}{29}\right)=\frac{352-(210+120)}{29}=\frac{22}{29}\).
Ответ: а) \(1\frac{1}{2}\); б) \(11\frac{13}{25}\); в) \(\frac{23}{31}\); а) \(9\frac{1}{3}\); б) \(10\frac{11}{24}\); в) \(\frac{22}{29}\).
