What are the least number of ninths you would need to have more than a half?
We know that a half is 1/2 as a fraction, but we can multiply the numerator and denominator by 9 and 1/2 is 9/18. The least number of ninths we can add is 1. So we add 1/9 + 9/18 which is 2/18+9/18 or 11/18. We can write this as (11/2)/9 or 5.5/9 which is 5.5 ninths.

How is 0 1 4 9and 16 a pattern?
the next number in the sequence is 25............starting at the beginning, you add the odd numbers to the existing number to get the answer. Add "1" to 0, get 1; add "3" to 1, get 4; add "5" to 4, get 9; add "7" to 9 to get 16........and add "9" to 16 to get 25.........
