100
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.
It is a ratio of 5:13
If you restrict yourself to natural numbers, it is 25/25 = 1/1.
set of all even natural numbers less than 10 = {2, 4, 6, 8}
Assuming you refer to positive integers, the answer is 10:9
An infinite number of even numbers are less than 10.

As N approaches infinity the ratio of squares less than N to numbers with 4 factors less than N approaches 0. This means that in the customary way of defining it, the ratio you're interested in is 0 (although that should be taken with a grain of salt - it certainly doesn't mean that there are 0 square numbers). The number of squares less than N is approximately √N. Rather than calculating the ratio we're interested in, we're going to calculate a calculate a ratio guaranteed to be greater: the ratio of squares to numbers that are twice a prime number (which are some, but not all, of the numbers with 4 factors). There are approximately N/ln N prime numbers less than N, by the prime number theorem. So there are N/(2 ln N/2) prime numbers less than N/2, which can be doubled to get a number less than N that's twice a prime number. The ratio is therefore √N(2 ln N/2)/N, which is O(ln N/√N). √N grows much faster than ln N, and in the limit this ratio will get close to zero. So the ratio we're actually interested in, which is even less than this ratio, will also approach zero.
Yes, a set of even numbers less than 8 would include the numbers 2, 4, and 6. Even numbers are integers that are divisible by 2, meaning they have a remainder of 0 when divided by 2. In this case, the even numbers less than 8 are 2, 4, and 6.
Set of even numbers less than 50 and more than 40 = {42,44,46,48}
The even whole numbers greater than 21 and less than 28 are: 22, 24 and 26
If you restrict yourself to natural numbers, it is 25/25 = 1/1.
There are no numbers between 70 and 85 that are less than 10. Not a single one. That goes for even numbers, odd numbers, mixed numbers, and decimals.

Assuming you refer to positive integers, the answer is 10:9
There are 49 even numbers less than 100, but only the number 2 is an even prime number less than 100.
