в) 3 2/11 + 1 5/11 =; г) 4 7/13 + 1/13 =; д) 2 + 6 3/17 =; е) 2 1/15 + 4 7/15 =

1. \(3\frac{2}{11}+1\frac{5}{11}= (3+1)+\frac{2+5}{11}=4\frac{7}{11}\).
2. \(4\frac{7}{13}+\frac{1}{13}=4\frac{8}{13}\).
3. \(2+6\frac{3}{17}=8\frac{3}{17}\).
4. \(2\frac{1}{15}+4\frac{7}{15}= (2+4)+\frac{1+7}{15}=6\frac{8}{15}\).

Ответ: в) \(4\frac{7}{11}\); г) \(4\frac{8}{13}\); д) \(8\frac{3}{17}\); е) \(6\frac{8}{15}\).
