Решение:
- \(3\frac{7}{10} = 3,7\)
- \(5\frac{18}{100} = 5,18\)
- \(11\frac{14}{1000} = 11,014\)
- \(19\frac{511}{10000} = 19,0511\)
- \(1,4 = 1\frac{4}{10} = 1\frac{2}{5}\)
- \(2,11 = 2\frac{11}{100}\)
- \(34,08 = 34\frac{8}{100} = 34\frac{2}{25}\)
- \(3 \text{ т } 74 \text{ кг } 48 \text{ г} = 3000 \text{ кг } + 74 \text{ кг } + 0,048 \text{ кг} = 3074,048 \text{ кг}\)
Ответ: 1) 3,7; 5,18; 11,014; 19,0511. 2) \(1\frac{2}{5}\); \(2\frac{11}{100}\); \(34\frac{2}{25}\). 3) 3074,048 кг.
