Question

Procedimiento del apartado d) y del e)

Answer 1

d) $( \frac{1}{3} - \frac{1}{2} ):( -\frac{2}{3} * \frac{1}{2} )- \frac{1}{4} =$

$( \frac{1*2}{6} - \frac{1*3}{6} ):( -\frac{2*1}{3*2})- \frac{1}{4} =$

$( \frac{2}{6} - \frac{3}{6} ):( -\frac{2}{6})- \frac{1}{4} =$

$( \frac{2-3}{6} ):( -\frac{2}{6})- \frac{1}{4} =$

$\frac{-1}{6}:(-\frac{2}{6})- \frac{1}{4} =$

$\frac{-1*6}{-2*6} - \frac{1}{4} =$

$\frac{-1}{-2} - \frac{1}{4} =$

$\frac{1}{2} - \frac{1}{4} =$

$\frac{2}{4} - \frac{1}{4} = \frac{1}{4}$

Solución: 1/4


e) $( \frac{1}{4} - \frac{1}{3} )*(- \frac{1}{3} - \frac{1}{2} )=$

$( \frac{1*3}{12} - \frac{1*4}{12} )*(- \frac{1*2}{6} - \frac{1*3}{6} )=$

$( \frac{3}{12} - \frac{4}{12} )*(- \frac{2}{6} - \frac{3}{6} )=$

$( \frac{3-4}{12} )*(\frac{-2-3}{6})=$

$( \frac{-1}{12} )*(\frac{-5}{6})=$

$( \frac{-1*(-5)}{12*6} )=\frac{5}{72}$

Solución: 5/72
