Because Vegeta's vagina was over-active. Stupid fertility drugs.
Since our numerical system is based upon 10 digits, every number divided by nine wil cause an infinite loop of numbers one over nine is 0.1111111... two over nine is 0.22222222... since eighth over nine is 0.888888888... nine over nine is 0.99999999... but nine over nine is 1 so in your case eleven over nine will cause a infinite loop of 1.222222222222222222... Point is an accurate decimal form of eleven over nine or any other digits over nine is impossible.
It is nine over seven.
five over nine
Zero.
Yes.
nine over twelve.
two over nine as a decimal = 2/9 = 0.2222
five over eight is less than nine over ten
1
No, it's improper.
If you mean (nine over ten) times two the answer is 6 over 5 If you mean nine over (ten times two) the answer is 3 over 10
Nine over 21 in its simplest form is 3/7
