Explicación paso a paso:

$B=(1\frac{1}{3} -\frac{3}{7} +\frac{5}{14} -\frac{1}{2})(3\frac{3}{11}+3\frac{1}{4} -1\frac{9}{33}) \\B=(1+\frac{1}{3} -\frac{3}{7} +\frac{5}{14} -\frac{1}{2})(3+\frac{3}{11}+3+\frac{1}{4} -(1+\frac{9}{33})) \\B=(\frac{3}{3} +\frac{1}{3} -\frac{3.2}{7.2} +\frac{5}{14} -\frac{1.7}{2.7})(3+\frac{3.3}{11.3}+3+\frac{1}{4} -1-\frac{9}{33})) \\B=(\frac{4}{3} -\frac{6}{14} +\frac{5}{14} -\frac{7}{14})(5+\frac{9}{33}+\frac{1}{4} -\frac{9}{33})) \\B=(\frac{4}{3} -\frac{8}{14})(5+\frac{1}{4})$

$B=(\frac{4}{3} -\frac{4}{7})(\frac{5.4}{1.4}+\frac{1}{4})\\B=(\frac{4.7}{3.7}-\frac{4.3}{7.3})( \frac{20}{4}+\frac{1}{4})\\B=(\frac{28}{21}-\frac{12}{21})(\frac{21}{4}) \\B=(\frac{16}{21})(\frac{21}{4})\\B=4$
