Respuesta:

$1)3 \frac{1}{2} + x + 1 \frac{5}{6} = 6 \frac{1}{2} \\ \frac{7}{2} + x + \frac{11}{6} = \frac{13}{2} \\ \frac{21}{6} + x + \frac{11}{6} = \frac{39}{6} \\ \frac{32}{6} + x = \frac{39}{6} \\ x = \frac{39}{6} - \frac{32}{6} \\ x= \frac{7}{6}$

$2)3 \frac{1}{4} - 2 \frac{1}{2} + c = 3 \frac{1}{6} \\ \frac{13}{4} - \frac{5}{2} + c = \frac{19}{6} \\ \frac{39}{12} - \frac{30}{12} + c = \frac{38}{12} \\ \frac{9}{12} + c = \frac{38}{12} \\ c = \frac{38}{12} - \frac{9}{12} \\ c = \frac{29}{12}$

$3)n + 2 \frac{1}{4} - \frac{7}{8} = 2 \frac{1}{2} \\ n + \frac{9}{4} - \frac{7}{8} = \frac{5}{2} \\ n + \frac{18}{8} - \frac{7}{8} = \frac{20}{8} \\ n = \frac{20}{8} - \frac{18}{8} + \frac{7}{8} \\ n = \frac{9}{8}$

$4)2 \frac{1}{2} + b + 5 \frac{1}{2} - 2 \frac{1}{4} = 7 \\ \frac{5}{2} + b + \frac{11}{2} - \frac{9}{4} = \frac{14}{2} \\ b = \frac{14}{2} - \frac{5}{2} - \frac{11}{2} + \frac{9}{4} \\ b = \frac{28}{4} - \frac{10}{4} - \frac{22}{4} + \frac{9}{4} \\ b = \frac{7}{4}$
