Решите задачу:

$2 \frac{3}{10} \times 1.1 = \frac{23}{10} \times 1 \frac{1}{10} = \frac{23}{10} \times \frac{11}{10} = \frac{253}{100} = 2 \frac{53}{100} = 2.53$

$\frac{71}{100} \times 6.3 = \frac{71}{100} \times 6 \frac{3}{10} = \frac{71}{100} \times \frac{63}{10} = \frac{71 \times 63}{100 \times 10} = \frac{4473}{1000} = 4 \frac{473}{1000} = 4.473$

$\frac{3}{5} \div 0.25 + 0.6 = 3 \\ \\ 1) \frac{3}{5} \div \frac{25}{100} = \frac{3}{5} \times \frac{100}{25} = \frac{3 \times 100}{5 \times 25} = \frac{3 \times 20}{1 \times 25} = \frac{60}{25} = 2.4 \\ \\ 2.4 + 0.6 = 3$

$1.6 \times \frac{1}{2} + 3.2 = 4 \\ 1)1.6 \times \frac{1}{2} = 1 \frac{6}{10} \times \frac{1}{2} = \frac{16}{10} \times \frac{1}{2} = \frac{16 \times 1}{10 \times 2} = \frac{8}{10} = 0.8 \\ \\ 2)0.8 + 3.2 = 4$
