Inheritance in the Quran.

[Muslimkid]

Assalamu alaikum.
I have a question on inheritance in the Quran (this might have been dealth with but just give me a link to the answer than)
Lets say i have: 2 alive parents, 3 daugthers, and a wife. now surah 4:11 and 4:12 say that my wife is to get 1/8, daugthers get 2/3 to share, and my dad and mom get 1/6 each
1/8=3/24
2/3=16/24
1/6=4/24
1/6=4/24

and all that equals in all 27/24... Is that a mathemathical error? I found this on facebook (someone had written this and im just wondering  ) Any help would be appreciated.

You should look at any explanation (Tafsir) of this and you'll have no problems . Just be careful with which explanations you choose to read .
