even numbers 1-100
101
Every second number is Even. So there are 50 even numbers from 1 to 100 if you include 100. If you do not include 100 in the count there are obviously 49. The wording of the question is not clear on whether 100 is to be included or not.
To find how many numbers between 1 and 100 inclusive are divisible by 2, we can identify the even numbers in that range. The even numbers from 1 to 100 are 2, 4, 6, ..., 100. This forms an arithmetic sequence where the first term is 2, the last term is 100, and the common difference is 2. There are 50 even numbers (2, 4, 6, ..., 100), so there are 50 numbers between 1 and 100 that are divisible by 2.
There are 25 such numbers.

There are 100 even numbers between 1 and 200 (inclusive).

Every second number is Even. So there are 50 even numbers from 1 to 100 if you include 100. If you do not include 100 in the count there are obviously 49. The wording of the question is not clear on whether 100 is to be included or not.
The only even prime number (not only from 1 to 100, but in general) is 2. All other even numbers are multiples of 2, and therefore, by definition, not prime numbers.
n*(n+1)=sum 100*(100+1)=10100
Every number has 1 as a multiple. 1*100 = 100 1*7 = 7 As 1 is an odd number there are no numbers with only even multiples.
There are 25 such numbers.
Since odd numbers are in a ratio of 1:2 it means for every one odd there will be one even, there would be 50 odd numbers between 1-100, and 50 even numbers. So 50%.
