Ответ:
- \(-2,(3)=-\left(2+\frac{3}{9}\right)=-\frac{7}{3}\).
- \(-5,0(6)=-\left(5+\frac{6}{90}\right)=-\frac{76}{15}\).
- \(-12,(124)=-\left(12+\frac{124}{999}\right)=-\frac{12112}{999}\).
- \(4,21(31)=4+\frac{21}{100}+\frac{31}{9900}=\frac{4171}{990}\).
- \(123,40(103)=123+\frac{40}{100}+\frac{103}{9900}=\frac{1221763}{9900}\).
- \(888,(89)=888+\frac{89}{99}=\frac{88001}{99}\).
Ответ: 1) \(-\frac{7}{3}\); 2) \(-\frac{76}{15}\); 3) \(-\frac{12112}{999}\); 4) \(\frac{4171}{990}\); 5) \(\frac{1221763}{9900}\); 6) \(\frac{88001}{99}\).
