Решение:
а) 2 \frac{3}{10} = 2 + \frac{3}{10} = 2 + 0.3 = 2.3
б) 3 \frac{1}{10} = 3 + \frac{1}{10} = 3 + 0.1 = 3.1
в) 6 \frac{20}{100} = 6 + \frac{20}{100} = 6 + 0.2 = 6.2
г) 7 \frac{100}{1000} = 7 + \frac{100}{1000} = 7 + 0.1 = 7.1
д) 21 \frac{25}{1000} = 21 + \frac{25}{1000} = 21 + 0.025 = 21.025
е) 45 \frac{6}{10} = 45 + \frac{6}{10} = 45 + 0.6 = 45.6
Ответ:
а) 2.3
б) 3.1
в) 6.2
г) 7.1
д) 21.025
