Задание 1 а) \(\frac{1}{8} + \frac{7}{12}\) б) \(1 - \frac{3}{4}\) б) \(5\frac{6}{4} + \frac{3}{4}\) г) \(5\frac{2}{3} - 1\frac{1}{4}\)

Ответ: а) \(\frac{13}{24}\); б) \(\frac{1}{4}\); в) 6 \(\frac{1}{4}\); г) 4 \(\frac{5}{12}\)

Решение:

1. а) \(\frac{1}{8} + \frac{7}{12} = \frac{3}{24} + \frac{14}{24} = \frac{17}{24}\)
2. б) \(1 - \frac{3}{4} = \frac{4}{4} - \frac{3}{4} = \frac{1}{4}\)
3. в) \(5\frac{6}{4} + \frac{3}{4} = 5 + \frac{6}{4} + \frac{3}{4} = 5 + \frac{9}{4} = 5 + 2\frac{1}{4} = 6\frac{1}{4}\)
4. г) \(5\frac{2}{3} - 1\frac{1}{4} = 5\frac{8}{12} - 1\frac{3}{12} = 4\frac{5}{12}\)

Ответ: а) \(\frac{13}{24}\); б) \(\frac{1}{4}\); в) 6 \(\frac{1}{4}\); г) 4 \(\frac{5}{12}\)
