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}
