Ответ:
Чтобы разделить на дробь, умножаем на обратную ей дробь. Смешанные числа сначала переводим в неправильные дроби.
- \(\frac{6}{25}:\frac{9}{5}=\frac{6}{25}\cdot\frac{5}{9}=\frac{2}{15}\).
- д) \(\frac{8}{27}:\frac{8}{9}=\frac{8}{27}\cdot\frac{9}{8}=\frac{1}{3}\).
- и) \(9\frac{5}{7}:1\frac{23}{28}=\frac{68}{7}:\frac{51}{28}=\frac{68}{7}\cdot\frac{28}{51}=\frac{272}{51}=5\frac{17}{51}\).
- б) \(6\frac{2}{3}:\frac{1}{8}=\frac{20}{3}\cdot 8=\frac{160}{3}=53\frac{1}{3}\).
- е) \(57:\frac{19}{24}=57\cdot\frac{24}{19}=72\).
- к) \(\frac{36}{47}:18=\frac{36}{47}\cdot\frac{1}{18}=\frac{2}{47}\).
- в) \(\frac{3}{8}:\frac{2}{3}=\frac{3}{8}\cdot\frac{3}{2}=\frac{9}{16}\).
- ж) \(\frac{14}{39}:\frac{21}{52}=\frac{14}{39}\cdot\frac{52}{21}=\frac{8}{9}\).
- л) \(\frac{16}{17}:8=\frac{16}{17}\cdot\frac{1}{8}=\frac{2}{17}\).
- г) \(4\frac{1}{11}:2\frac{19}{22}=\frac{45}{11}:\frac{63}{22}=\frac{45}{11}\cdot\frac{22}{63}=\frac{10}{7}=1\frac{3}{7}\).
- з) \(11\frac{2}{5}:3\frac{4}{5}=\frac{57}{5}:\frac{19}{5}=3\).
- м) \(12:\frac{6}{7}=12\cdot\frac{7}{6}=14\).
- а) \(\frac{3}{8}:\frac{9}{16}=\frac{3}{8}\cdot\frac{16}{9}=\frac{2}{3}\).
- б) \(4\frac{1}{2}:5\frac{1}{4}=\frac{9}{2}:\frac{21}{4}=\frac{9}{2}\cdot\frac{4}{21}=\frac{6}{7}\).
- в) \(48:\frac{12}{13}=48\cdot\frac{13}{12}=52\).
- г) \(\frac{15}{16}:5=\frac{15}{16}\cdot\frac{1}{5}=\frac{3}{16}\).
