Ответ:

1)

$\frac{4 \times 5}{25 \times 16} = \frac{1}{5 \times 4} = \frac{1}{20}$

2)

$\frac{12 \times 3}{ 14 \times 9} = \frac{6}{7 \times 3} = \frac{2}{7}$

3)

$\frac{1 \times 7}{28 \times 2} = \frac{1}{4 \times 2} = \frac{1}{8}$

4)

$\frac{16 \times 14 \times 3}{32 \times 15 \times 7} = \frac{2}{2 \times 5} = \frac{1}{5}$

5)

$\frac{24 \times 6}{12 \times 13 \times 24} = \frac{1}{2 \times 13} = \frac{1}{26}$

6)

$\frac{2 \times 6 \times 10}{5 \times 16 \times 21} = \frac{2 \times 2}{8 \times 7} = \frac{2}{4 \times 7} = \frac{1}{2 \times 7} = \frac{1}{14}$

7)

$\frac{5 \times 9 \times 45}{63 \times 125} = \frac{45}{7 \times 25} = \frac{9}{7 \times 5} = \frac{9}{35}$

8)

$\frac{20 \times 55 \times 13}{52 \times 110 \times 7} = \frac{20}{4 \times 2 \times 7} = \frac{5}{2 \times 7} = \frac{5}{14}$
