How much money should I get [closed]

I own $20\%$ of a sum of money with my partner who owns the other $80\%$. My partner needs $\$4156.73$how much should I get? My partner says I should get$\$831.35$. He simply multiplied the $\$4156.73$by$20\%$. I said I was owed$\$1039.18$ which I figured by dividing the $\$4156.73$by$8$and multiplying that answer by$2$. Sorry to those that thought I was being LAZY, this was my first time using this website and did not know how the routine. Thanks to everyone who responded. - You should not be getting that much money if you cannot even compute your share. – TMM Jun 2 '13 at 19:24 Easy guys, this is his first question. – Shuhao Cao Jun 2 '13 at 19:25 i dont see why this gets downvoted? math on all levels right? – WiseStrawberry Jun 2 '13 at 19:27 @Wise: On all levels, it is also stimulated that people who ask questions include their own attempts, and where they are having problems. We are here to help them solve their problems, not to show that we know how to solve this problem. – TMM Jun 2 '13 at 19:42 To get anywhere with this you need to say something about sharing everything in proportion 20/80, not just the sum of money you already have. At the moment it is not clear what you are asking. You might need no money ... – Mark Bennet Jun 2 '13 at 19:44 show 1 more comment closed as too localized by Zev Chonoles, O.L., TMM, Amzoti, JoeJun 2 '13 at 20:28 This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet.

If your partner owns 80% (0.80), and we know his share is 4156.73, then we can say that 80% of S is \$4156.73;

mathematically, that's written 0.80*S=4156.73

Solve for S by dividing both sides by 0.80, and S = 5195.9125 (Round to 5195.91, since we're dealing with money.)

Now, since 4156.73 is your partner's, the remaining amount must be yours, so

5195.91 - 4156.73 = 1039.18 is your share.

Alternatively, since you own 20% (0.20) of the total sum S, you can solve algebraically by

0.20*S = 0.20 * 5195.91 = 1039.18 is your share.
