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

1. \(\frac{24}{37}-\frac{8}{37}+\frac{11}{37}=\frac{24-8+11}{37}=\frac{27}{37}\).
2. \(3\frac{7}{11}+6\frac{3}{11}-5\frac{5}{11}=14\frac{10}{11}-5\frac{5}{11}=9\frac{5}{11}\).
3. \(1-\frac{7}{15}=\frac{15}{15}-\frac{7}{15}=\frac{8}{15}\).
4. \(5\frac{3}{8}-2\frac{5}{8}=2\frac{11}{8}-2\frac{5}{8}=2\frac{6}{8}=2\frac{3}{4}\).

Ответ: 1) \(\frac{27}{37}\); 2) \(9\frac{5}{11}\); 3) \(\frac{8}{15}\); 4) \(2\frac{3}{4}\).
