592. Замените данное отношение отношением натуральных чисел: 1) $$1:\frac{3}{8}$$; 2) $$12:\frac{5}{18}$$; 3) $$4:\frac{3}{5}$$; 4) $$1\frac{1}{3}:1\frac{1}{3}$$

1. $$1:\frac{3}{8} = \frac{1}{1}:\frac{3}{8} = \frac{1 \cdot 8}{1 \cdot 8}:\frac{3}{8} = \frac{8}{8}:\frac{3}{8} = 8:3$$
2. $$12:\frac{5}{18} = \frac{12}{1}:\frac{5}{18} = \frac{12 \cdot 18}{1 \cdot 18}:\frac{5}{18} = \frac{216}{18}:\frac{5}{18} = 216:5$$
3. $$\frac{3}{4}:\frac{3}{5} = \frac{3 \cdot 5}{4 \cdot 5}:\frac{3 \cdot 4}{5 \cdot 4} = \frac{15}{20}:\frac{12}{20} = 15:12 = 5:4$$
4. $$1\frac{1}{3}:1\frac{1}{3} = \frac{4}{3}:\frac{4}{3} = 1:1$$

Ответ:

1. 8:3
2. 216:5
3. 5:4
4. 1:1
