Решите задачу:

$1) \: \: \: \frac{15 \times 7}{30 \times 4} = \frac{7}{2 \times 4} = \frac{7}{8} \\ 2) \: \: \: \frac{15 \times 11}{18 \times 33} = \frac{5}{6 \times 3} = \frac{5}{18}$
$3) \: \: \: \frac{7 \times 9 \times 25}{21 \times 3 \times 50} = \frac{3}{3 \times 2} = \frac{1}{2} \\ 4) \: \: \: \frac{16 \times 13 \times 23}{69 \times 8 \times 26} = \frac{2 }{3 \times 2} = \frac{1}{3}$
$5) \: \: \: \frac{29 \times 5 \times 13}{52 \times 20 \times 58} = \frac{1}{4 \times 4 \times 2} = \frac{1}{32} \\ 6) \: \: \: \frac{37 \times 39 \times 75}{111 \times 42 \times 100} = \frac{13 \times 3}{3 \times 14 \times 4} = \frac{13}{56}$
