Explicación paso a paso:

$( \frac{5}{2} + 1 \frac{1}{3}) - (1 \frac{1}{4}) = ( \frac{5}{2} + \frac{4}{3}) - \frac{5}{4} = \frac{15 + 8}{6} - \frac{5}{4} = \frac{23}{6} - \frac{5}{4} = \frac{92 - 30}{24} = \frac{62}{24} = \frac{31}{12} = 2 \frac{7}{12}$

$(3 \frac{1}{8})(2 \frac{1}{3}) \div (1 \frac{2}{3}) = ( \frac{25}{8})( \frac{7}{3}) \div \frac{5}{3} = \frac{175}{24} \div \frac{5}{3} = \frac{175}{24} \times\frac{3}{5} = \frac{525}{24} = \frac{35}{8} = 4 \frac{3}{8}$

$(5 \frac{1}{3}) \div ( \frac{3}{7}) + (1 \frac{1}{4}) = \frac{16}{3} \div \frac{3}{7} + \frac{5}{4} = \frac{16}{3} \times \frac{7}{3} + \frac{5}{4} = \frac{112}{9} + \frac{5}{4} = \frac{448+45}{36} = \frac{493}{36} = 13 \frac{25}{36}$

$(3 \frac{1}{2}) - (1 \frac{1}{3}) \times ( \frac{4}{3}) = \frac{7}{2} - \frac{4}{3} \times \frac{4}{3} = \frac{7}{2} - \frac{16}{9} = \frac{63 - 32}{18} = \frac{31}{18} = 1 \frac{13}{18}$

$(3 \frac{2}{7} \times 1 \frac{2}{3}) \div ( \frac{3}{5} ) = ( \frac{23}{7} \times \frac{5}{3}) \div \frac{3}{5} = \frac{115}{21} \div \frac{3}{5} = \frac{115}{21} \times \frac{5}{3} = \frac{575}{63} = 9 \frac{8}{63}$
