Solve the following fraction problems: 1/9 1/2 1/3 3/4 5/6 9/10 1/4 2/5 1/6 7/8 1/4 2/3 7/10 1/20 28/36 19/36 2+7/8 4/8 6/8 4/8 8/12 10/12 2+3/12 3/4

Решение:

Будем решать примеры по колонкам, сверху вниз.

Первая колонка:

1. \(\frac{1}{9}\)
2. \(\frac{1}{2}\)
3. \(\frac{1}{3}\)
4. \(\frac{3}{4}\)
5. \(\frac{5}{6}\)
6. \(\frac{9}{10}\)

Вторая колонка:

1. \(\frac{28}{36} = \frac{7}{9}\)
2. \(\frac{19}{36}\)
3. \(\frac{1}{4} + \frac{2}{5} = \frac{5}{20} + \frac{8}{20} = \frac{13}{20}\)
4. \(\frac{1}{4}\)
5. \(\frac{1}{6}\)
6. \(\frac{7}{8}\)
7. \(\frac{1}{4} + \frac{1}{2} = \frac{1}{4} + \frac{2}{4} = \frac{3}{4}\)
8. \(\frac{1}{20}\)

Третья колонка:

1. \(\frac{2}{7} + \frac{9}{8} = \frac{16}{56} + \frac{63}{56} = \frac{79}{56}\)
2. \(\frac{4}{8} = \frac{1}{2}\)
3. \(\frac{6}{8} = \frac{3}{4}\)
4. \(\frac{4}{8} = \frac{1}{2}\)
5. \(\frac{2}{3} + \frac{1}{4} = \frac{8}{12} + \frac{3}{12} = \frac{11}{12}\)
6. \(\frac{10}{12} = \frac{5}{6}\)
7. \(\frac{2+3}{12} = \frac{5}{12}\)

Четвертая колонка:

1. \(\frac{8}{12} + \frac{3}{12} = \frac{11}{12}\)
2. \(\frac{2+3}{12} = \frac{5}{12}\)
3. \(\frac{1}{20}\)

Ответ: Приведены решения по колонкам.
