En la 3)
= [tex]\frac{\frac{2}{3}+\frac{1}{2} }{3 - 2 } x ( \frac{47}{2} / \frac{47}{12})[/tex]
= [tex]\frac{\frac{7}{6} }{1} x ( \frac{282}{47} )[/tex]
= [tex]\frac{7}{6} x \frac{282}{47}[/tex]
= [tex]\frac{1974}{282}[/tex] = 4
En la 4)
= [tex]\frac{\frac{1}{\frac{4}{5} } + \frac{1}{\frac{5}{6} } }{\frac{1}{\frac{2}{3} }- \frac{1}{\frac{7}{8} } } x ( \frac{9}{49} - \frac{62}{343} )[/tex]
= [tex]\frac{\frac{5}{4}+ \frac{6}{5} }{\frac{3}{2}+ \frac{8}{7} } x ( \frac{1}{343} )[/tex]
= [tex]\frac{\frac{49}{20} }{\frac{37}{14} } x \frac{1}{343}[/tex]
= [tex]\frac{686}{740} x \frac{1}{343}[/tex]
= [tex]\frac{1}{370}[/tex]
