1) $\frac{4}{11}+\frac{6}{11} = \frac{10}{11}$ (4/11 + 6/11 = 10/11)
2) $\frac{7}{25} + \frac{2}{25} = \frac{9}{25}$ (7/25 + 2/25 = 9/25)
3) $\frac{1}{9} + \frac{5}{9} = \frac{6}{9} = \frac{2}{3}$ (1/9 + 5/9 = 6/9 = 2/3)
4) $\frac{8}{100} + \frac{34}{100} = \frac{42}{100} = \frac{21}{50}$ (8/100 + 34/100 = 42/100 = 21/50)
