A statistics problem I need help with - Iraqi "Election"

[sportndandy]

I am not good with numbers, so I was hoping someone could help.

Number of registered voters = ?
Percentage of registered who voted = 57%
Number of registered exiles = 280,000
Number of exile voters = 265,000

With these numbers, is it possible to figure out how many Iraqi's were registered inside Iraq, and how many actually voted? I am assuming that the exiles is a subset of the total registered vote. Of course, all this assumes that the numbers I am using are even accurate. I got them off of Michael Moore's site.

1. If you knew either the number of registered in Iraq or

the number who voted in Iraq, then yes. Otherwise no.

2. You need one more number, I think

It's algebra. (Don't be afraid -- algebra is your friend.)

(voters abroad + voters inside) = 0.57*(registered abroad +registered inside)

You need one of the numbers for those inside Iraq to solve for the remaining number.

3. Do you think it's safe to assume that everyone who voted was registered?

6. Dunno. In Sunni Arab areas they had same day registration. n/t

4. According to NPR news report the day after the election...

...8,000,000 of the 14,000,000 eligable voters took part in the election in Iraq. So if we assume that the Iraqis overseas including those in the U.S. were part of those numbers than the figures should look like this:

Iraqi Election Summary

Total 14000000 8000000 57.1%

5. Post has 18 million eligible voters

According to the Washington Post, there are 18 million eligible voters compared to 14 million registred voters. See http://www.washingtonpost.com/wp-dyn/nation/columns/kurtzhoward/ If the 18 million number is correct, then the true turnout is much lower than reported.

7. Well if that's the case the voting base drops from 57.1% to 44.4%

...however, Iraqi demographics show that voting age adults are as follows:
