Explicación paso a paso:

1)

$3 \frac{1}{3} + 2 \frac{1}{4}$

$(3 + 2) + ( \frac{1}{3} + \frac{1}{4} )$

$5 + ( \frac{4 + 3}{12} )$

$5 + \frac{7}{12} = 5 \frac{7}{12}$

2)

$2 \frac{1}{3} + 3 \frac{2}{5}$

$(2 + 3) + ( \frac{1}{3} + \frac{2}{5} )$

$5 + ( \frac{5 + 6}{15} )$

$5 + \frac{11}{15} = 5 \frac{11}{15}$

3)

$1 \frac{1}{4} + 1 \frac{1}{5} + 1 \frac{1}{2}$

$(1 + 1 + 1) + ( \frac{1}{4} + \frac{1}{5} + \frac{1}{2} )$

$3 + ( \frac{5 + 4 + 10}{20} )$

$3 + \frac{19}{20} = 3 \frac{19}{20}$

4)

$3 \frac{1}{5} + 5 \frac{1}{2} + 7 \frac{5}{6}$

$(3 + 5 + 7) + ( \frac{1}{5} + \frac{1}{2} + \frac{5}{6} )$

$15 + ( \frac{6 + 15 + 25}{30} )$

$15 + \frac{46}{30}$

$15 + 1 \frac{8}{15} = 16 \frac{8}{15}$
