Hey guys i just need to know something really quick whats 6-2/5-8
I got 38/40
But my answer sheet shows something else please explain.
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:
$\displaystyle 6 - \frac{2}{5} - 8 = \frac{30 - 2 - 40}{5} = -\frac{12}{5}$
