Question 1079059: When I solve -(-2)/(2(-1/3)) I get -1/3 but my book and several online calculators all say -3. The only way to get -3 is to not use a reciprocal for the last step but that goes against the rules of division. Which is correct -2/2/3=(-2/2)(1/3) or -2/2/3=(-2/2)(3/1) ?
Aren't I supposed to multiply by the reciprocal when dividing fractions like in -2/2/3? Found 2 solutions by Boreal, MathTherapy:Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! That is 2/-(2/3)=-3
The parentheses matter. You can cancel the numerator and denominator +2, and you then have 1/(-1/3), and that is -3.
The numerator is clearly +2
the denominator is 2*-1/3=-2/3
When you divide, you take the reciprocal of the denominator and multiply.
