1) \(3\frac{5}{11}-1\frac{5}{11} = 2\)
2) \(1\frac{1}{4}+1\cdot\frac{1}{4} = 1\frac{1}{2} = \frac{3}{2}\)
3) \(-\frac{1}{4} + \frac{3}{2} = \frac{-1 + 3 \cdot 2}{4} = \frac{-1+6}{4} = \frac{5}{4}\)
4) \(2 + \frac{5}{4} = \frac{2 \cdot 4 + 5}{4} = \frac{8+5}{4} = \frac{13}{4} = 3\frac{1}{4}\)
Ответ: \(3\frac{1}{4}\)
