An election poll predicts tht, in one riding, 4 out of 7 voters will vote for a certain political party. There are 25 156 voters. If the prediction is true, how many voters will NOT vote for that political party.???? Im not only looking for the answer, however, im wondering HOW to find the answer.
THANKS IN ADVANCE!!!

3/7 times the total number of voters...

You know that 100% of voters will either against or for the political party in question. Since 4/7 of voters will vote for the political party, 3/7 will not vote for the political party of interest. You must the multiply (3/7)*25,156. you first multiply 3*25,156 and then divide by 7, which yields 10781.14.
.14 voters can vote, obviously; therefore, you would need to round down to reflect a whole number.

10781 will not vote for the political party.
First of all, according to your statistics 4/7 (four sevenths) of the voters will vote for the political party - that means that 3/7 (three sevenths) will not. In order to get the correct answer, divide the total number of voters by 7 and then multiply the answer by 3.
24156 divided by 7 = 3593.7
3593.7 x 3 = 10781.1 or when rounded = 10781

Divide 25 156 by 7. Now multiply the remainder, including any fraction if it didn't come out even, by 3 (7-4). If you still have a fraction, round it up or down. Be sure to show your work, so that your teacher sees that you got the exact answer but are aware that a fraction of a person can't vote.

4 out of 7; look at that as 4/7.
Divide the number of voters (25,156) by the divisor of voters (7). 25,156/7 = 3,593.714blahblahblah
4 out of 7 (or 4 * 3,593.714blahblahblah) equals the number of voters that would vote for them.
So 3 out of 7 (or 3 * 3,593.714blahblahblah) is the number of voters that would NOT vote for them.
NOTE: Let's call 3,593.714blahblahblah "x" for right now. To check your work, 4*x + 3*x should equal 25,156 (because 4 + 3 = 7, the divisor of the voters.)
hope this helps.
Check the number of voters - it is a little odd that you would be given a problem like this that wouldn't have whole numbers.
F'rinstance, if the total number of voters were 25,256, then the number would divide by 7, producing a tidy little number like 3,608.

divide the number of voters by 7, then find out how many won't vote by multiplying by 4. It's like 3/7 of 25156 (what's left without those who did vote for the party).

Use fractions or decimals and find the one first. Multiply 25,156 by 4/7 or .571 = 14,375. Now that's how many will vote FOR the party. Not for the party is either 25, 156 - 14,275 or 25,156 times 3/7 or .429 they should all equal 10,781.

okay, this is a simple ratio proble. You want to find out how many are NOT voting for a party, so first you find how many ARE voting for the political party. To do this you create a ratio.
4/7 = x/25156. then you cross multipy so,
100623= 7x now, divide by 7, and you have
x= 14374.9. so about 14375 voters voted FOR the polical party, because 14375/25156 is roughly 4/7.
Now you subtrat 14375 from 25156, and that's 10781.
So 10781 people DON'T vote for the political party.

A simple question. Beacuse 4/7 will vote for the party, 3/7 wont. (3/7+4/7=1) The answer is approx. 4791.

divide 25156 voters by 7. Then multiply that by 3, as 3 are not voting for that party
