Is that $\displaystyle \frac{6 - 2}{5 - 8}$ ?

If so, just do the subtractions and take the minus sign to the top to get $\displaystyle -\frac{4}{3}$

Or $\displaystyle 6 - \frac{2}{5} - 8$?

Put it all over a common denominator:

$\displaystyle 6 - \frac{2}{5} - 8 = \frac{30 - 2 - 40}{5} = -\frac{12}{5}$ - Jan 12th 2009, 12:37 PMmr fantastic
