Ответ:
Чтобы разделить дробь на натуральное число, умножаем её знаменатель на это число. Целые и смешанные числа сначала представляем в виде дробей.
| А: деление на 2 | Б: деление на 3 | В: деление на 5 |
|---|---|---|
| \(\frac{4}{9}:2=\frac{2}{9}\) | \(\frac{5}{8}:3=\frac{5}{24}\) | \(\frac{5}{7}:5=\frac{1}{7}\) |
| \(\frac{3}{7}:2=\frac{3}{14}\) | \(\frac{18}{19}:3=\frac{6}{19}\) | \(\frac{2}{9}:5=\frac{2}{45}\) |
| \(5:2=2\frac{1}{2}\) | \(2:3=\frac{2}{3}\) | \(\frac{1}{4}:5=\frac{1}{20}\) |
| \(\frac{10}{11}:2=\frac{5}{11}\) | \(\frac{9}{10}:3=\frac{3}{10}\) | \(\frac{20}{21}:5=\frac{4}{21}\) |
| \(1\frac{1}{3}:2=\frac{2}{3}\) | \(1\frac{1}{2}:3=\frac{1}{2}\) | \(6:5=1\frac{1}{5}\) |
| \(\frac{7}{8}:2=\frac{7}{16}\) | \(2\frac{2}{5}:3=\frac{4}{5}\) | \(\frac{25}{27}:5=\frac{5}{27}\) |
| \(\frac{16}{17}:2=\frac{8}{17}\) | \(\frac{6}{11}:3=\frac{2}{11}\) | \(2:5=\frac{2}{5}\) |
| \(\frac{1}{2}:2=\frac{1}{4}\) | \(\frac{4}{9}:3=\frac{4}{27}\) | \(1\frac{1}{5}:5=\frac{6}{25}\) |
| \(3:2=1\frac{1}{2}\) | \(1:3=\frac{1}{3}\) | \(\frac{10}{11}:5=\frac{2}{11}\) |
| \(1\frac{1}{7}:2=\frac{4}{7}\) | \(\frac{12}{17}:3=\frac{4}{17}\) | \(0:5=0\) |
| \(\frac{1}{3}:2=\frac{1}{6}\) | \(\frac{1}{2}:3=\frac{1}{6}\) | \(\frac{7}{12}:5=\frac{7}{60}\) |
| \(\frac{2}{5}:2=\frac{1}{5}\) | \(\frac{3}{7}:3=\frac{1}{7}\) | \(\frac{15}{17}:5=\frac{3}{17}\) |
| \(\frac{3}{4}:2=\frac{3}{8}\) | \(\frac{2}{5}:3=\frac{2}{15}\) | \(1:5=\frac{1}{5}\) |
| \(\frac{8}{11}:2=\frac{4}{11}\) | \(5:3=1\frac{2}{3}\) | \(\frac{9}{20}:5=\frac{9}{100}\) |
| \(1:2=\frac{1}{2}\) | \(\frac{15}{16}:3=\frac{5}{16}\) | \(\frac{35}{79}:5=\frac{7}{79}\) |
