Сократите дроби; 1) 28/70 2) 0,625 3) 25•39/35•13 4) 48/84 5)0,375 6) 7•12/30•21

Решите задачу:

$1) \frac{28}{70} = \frac{2}{5} \\ \\ 2) 0,625= \frac{625}{1000} = \frac{5}{8} \\ \\ 3) \frac{25*39}{35*13}= \frac{975}{455} = 2 \frac{1}{7} \\ \\ 4) \frac{48}{84}= \frac{4}{7} \\ \\ 5) 0,375= \frac{375}{1000}= \frac{3}{8} \\ \\ 6) \frac{7*12}{30*21} = \frac{84}{630}= \frac{2}{15}$
