winner: 3/7, leaving 4/7
runner-up: 5/8 * 4/7 = 5/14
loser: 1 - 3/7 - 5/14 = 3/14
total: 3/7 x = 5/14 x + 3021

I need an answer to this equation
In an election there were three candidates .3/7 of the electors voted for the winner . The runner up received 5/8 of the remaining votes.
A) what fraction of the electors voted for the third cadidate.
B) if the winner recieved 3021 voted than the runner up how many electors voted
Let's say that there were x electors in total.

3/7 of them voted for the winner, so that's 3/7x votes.

That leaves 4/7x electors remaining.

The runner-up received 5/8 of the remaining votes, which is (5/8) * (4/7x) = 5/14x votes.

That leaves (4/7x - 5/14x) = 3/14x votes for the third candidate.

We're also told that the winner received 3021 more votes than the runner-up, so:

3/7x = 5/14x + 3021

Multiplying both sides by 14 (the least common multiple of 7 and 2), we get:

6x = 5x + 42,294

Simplifying, we get:

x = 42,294

So there were 42,294 electors in total.

To find out what fraction of the electors voted for the third candidate, we need to divide their votes (3/14x) by the total number of electors (42,294):

(3/14) * (42,294) = 9,078

So 9,078 electors (or 3/14 of the total) voted for the third candidate.
