Edgar Guest Posted May 22, 2015 at 09:18 PM Report Share Posted May 22, 2015 at 09:18 PM Moral of the story: don't try to round 2/3. Take the number of voters and multiply by 2 and divide by 3. Stop the madness. Divide by 3 (the denominator) and multiply by 2 (the numerator). You divide by 3 to find out what number constitutes a third. Then you multiply that number by 2 to find out what number constitutes two thirds. If you first multiply by 2, what does that number represent? And don't say, "twice the number of voters".

Gary Novosielski Posted May 26, 2015 at 06:56 PM Report Share Posted May 26, 2015 at 06:56 PM Just don't multiply by 3 and divide by 2, or nothing will ever pass. Since multiplication is commutative, the most foolproof way is to take the reciprocal of the divisorand then you may multiply in any order you like. 2 * 1/3 or 1/3 * 2.

Say what? Speak English, man, for those of us who weren't math majors! Link to comment Share on other sites More sharing options...
