2011 AMC 10B Problems/Problem 1

Revision as of 00:00, 27 February 2011 by Patmaster (talk | contribs)

First, simplify the fractions.

$\dfrac{2+4+6}{1+3+5} - \dfrac{1+3+5}{2+4+6} = \dfrac{12}{9} - \dfrac{9}{12}$

$\dfrac{12}{9} - \dfrac{9}{12} = \dfrac{48}{36} - \dfrac{27}{36} = \dfrac{21}{36} = \dfrac{7}{12}$

$(C) \dfrac{7}{12}$
