2. Выполните действия: 1) 24/37 + 8/37 + 11/37; 3) 1 - 7/15; 2) 3 7/11 + 6 3/11 - 5 5/11; 4) 5 3/8 - 2 5/8.

1) \(\frac{24}{37} + \frac{8}{37} + \frac{11}{37} = \frac{24 + 8 + 11}{37} = \frac{43}{37} = 1 \frac{6}{37}\) 2) \(3 \frac{7}{11} + 6 \frac{3}{11} - 5 \frac{5}{11} = (3 + 6 - 5) + (\frac{7}{11} + \frac{3}{11} - \frac{5}{11}) = 4 + \frac{7 + 3 - 5}{11} = 4 + \frac{5}{11} = 4 \frac{5}{11}\) 3) \(1 - \frac{7}{15} = \frac{15}{15} - \frac{7}{15} = \frac{15 - 7}{15} = \frac{8}{15}\) 4) \(5 \frac{3}{8} - 2 \frac{5}{8} = (5 - 2) + (\frac{3}{8} - \frac{5}{8}) = 3 - \frac{2}{8} = 2 + \frac{8}{8} - \frac{2}{8} = 2 \frac{6}{8} = 2 \frac{3}{4}\)
