1) 4 - 5 1 2 1 5 10 3 8 1 6 7 15 17 46 14 8 13 13 =

Решение:

1. \( \frac{1}{4} - \frac{1}{5} = \frac{5-4}{20} = \frac{1}{20} \)
2. \( \frac{2}{5} - \frac{1}{10} = \frac{4-1}{10} = \frac{3}{10} \)
3. \( \frac{3}{8} - \frac{1}{6} = \frac{9-4}{24} = \frac{5}{24} \)
4. \( 11 - \frac{7}{15} = \frac{165-7}{15} = \frac{158}{15} \)
5. \( 32\frac{17}{46} - 14 = 18\frac{17}{46} = \frac{18 \cdot 46 + 17}{46} = \frac{828 + 17}{46} = \frac{845}{46} \)
6. \( 3\frac{8}{13} - \frac{13}{13} = 3\frac{8}{13} - 1 = 2\frac{8}{13} \)

Ответ: $$\frac{1}{20}$$; $$\frac{3}{10}$$; $$\frac{5}{24}$$; $$\frac{158}{15}$$; $$\frac{845}{46}$$; $$2\frac{8}{13}$$.
