Question

2(1/4-1/2)+3(1/3-1/2)-4(2-1/3)

Answer 1

$2( \frac{1}{4}- \frac{1}{2})+3( \frac{1}{3} - \frac{1}{2})-4(2- \frac{1}{3}) = \\ \\ 2( \frac{1}{4}- \frac{2}{4})+3( \frac{2}{6} - \frac{3}{6})-4( \frac{6}{3}- \frac{1}{3}) = \\ \\ 2( -\frac{1}{4})+3( -\frac{1}{6})-4( \frac{5}{3}) = \\ \\ -\frac{1}{2} -\frac{1}{2}- \frac{20}{3} = \\ \\ -\frac{3}{6} -\frac{3}{6}- \frac{40}{6} = \oxed{- \frac{46}{6}}= \boxed{ - \frac{23}{3}}$
