Сократите дробь:
а) $\frac{53 * 17}{41 * 17}$;
б) $\frac{64 * 15}{72 * 30}$;
в) $\frac{55 * 18}{24 * 33}$;
г) $\frac{42 * 81}{56 * 27}$;
д) $\frac{25 * 32}{40 * 35}$;
е) $\frac{16 * 48}{24 * 32}$;
ж) $\frac{42 * 44}{77 * 12}$;
з) $\frac{38 * 45}{81 * 57}$.
$\frac{53 * 17}{41 * 17} = \frac{53}{41} = 1\frac{12}{41}$
$\frac{64 * 15}{72 * 30} = \frac{8 * 8 * 15}{8 * 9 * 2 * 15} = \frac{8}{9 * 2} = \frac{4 * 2}{9 * 2} = \frac{4}{9}$
$\frac{55 * 18}{24 * 33} = \frac{11 * 5 * 3 * 6}{4 * 6 * 3 * 11} = \frac{5}{4} = 1\frac{1}{4}$
$\frac{42 * 81}{56 * 27} = \frac{14 * 3 * 3 * 27}{14 * 4 * 27} = \frac{3 * 3}{4} = \frac{9}{4} = 2\frac{1}{4}$
$\frac{25 * 32}{40 * 35} = \frac{5 * 5 * 8 * 4}{8 * 5 * 5 * 7} = \frac{4}{7}$
$\frac{16 * 48}{24 * 32} = \frac{16 * 24 * 2}{24 * 16 * 2} = 1$
$\frac{42 * 44}{77 * 12} = \frac{6 * 7 * 4 * 11}{7 * 11 * 6 * 2} = \frac{4}{2} = 2$
$\frac{38 * 45}{81 * 57} = \frac{19 * 2 * 9 * 5}{9 * 9 * 19 * 3} = \frac{2 * 5}{9 * 3} = \frac{10}{27}$
