so that the total count will result in a vote of 2 to 1 against the resolution? what does this mean in mathematical language ?
Hi Dip050701,
If you are approaching this question algebraically - and you choose specific variables to refer to "for" and "against" (for example... "F" = the number of votes FOR the resolution and "A" = the number of votes AGAINST the resolution), then 2 to 1 against would be F/A = 2/1.
Of course, you can approach this question in a number of different ways (which you'll see in the other posts in this thread). Since the arithmetic involved is fairly simple, I chose to TEST VALUES. Here's how:
Since we're dealing with 'ninths' and 'fourths', let's TEST a common denominator: 36
For the final ratio to be 2:1 AGAINST the resolution, we need there to be 24 votes AGAINST and 12 votes in FAVOR
IF.... there are 36 total votes
(2/9)(36) = 8 votes have been counted
(3/4)(8) = 6 of those 8 votes are in FAVOR of the resolution.... and the other 2 votes are AGAINST
36 - 8 = 28 votes remain
Since we already have 2 votes in AGAINST - and we need 24 total votes AGAINST, we need 22 of these remaining 28 votes to be AGAINST (and then the rest will be in FAVOR).
22/28 = 11/14
