Assuming you refer to positive integers, the answer is 10:9
It is 0 since the number of odd numbers less than 180 is infinite and a finite number "divided by infinity" is zero. However, if you limit yourself to positive integers, then the ratio is 49/90, which cannot be simplified.
ratio
The ratio is 1:2. For every even number there are 2 odd numbers. Fibonacci Series: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ... which is even, odd, odd, even, odd, odd, even, odd, odd, even, ... the pattern continues
All numbers are either odd or even, none are both, so less than 30 there are 29 counting numbers that are either odd or even but not both. (Assuming you mean starting to count with 1.)
None. All counting numbers are even or odd.

ratio
The ratio of odd numbers to even numbers is 1 : 1 or 50-50.
Odd. First subtract 1 less than your odd number, (which is obviously even) to get even - even, which is even. Then take off your spare 1 to finish up odd.

None. All counting numbers are even or odd.
If you restrict yourself to natural numbers, it is 25/25 = 1/1.
There are four odd numbers less that 100 that have 6 factor. This does not compare with even numbers that have 12 factors!
if the numbers are from 1 - 9 then the ratio of even to odd is 4:5 (2, 4, 6 & 8 are even, 1, 3, 5, 7 & 9 are odd)
If it's a Even Number it stays an Even Mumber However if it's a odd it stays an Odd AntF6
