сократите дроби ​

Answer 1

Ответ:

$\frac{25 \times 99}{81 \times 55} = \frac{5 \times 11}{9 \times 11} = \frac{5}{9}$

$\frac{49 \times 22 \times 25}{33 \times 28 \times 35} = \frac{7 \times 2 \times 5}{3 \times 4 \times 7} = \frac{5}{6}$

$\frac{18 \times 45}{75 \times 27} = \frac{6 \times 9}{15 \times 9} = \frac{6}{15}$

$\frac{12 \times 33 \times 25 }{55 \times 8 \times 45} = \frac{3 \times 3 \times 5}{5 \times 2 \times 9} = \frac{3}{6} = \frac{1}{2}$
