There are an infinite amount of numbers between 1 and 2
1.5
0.1, 0.25 and 0.674 but note that there are thousands of decimals between 0 to 1.
A number with no decimals is an integer which is a whole number
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. No decimals will be odd or even.
Numbers are infinite, as a matter of fact counting decimals there are a infinite amount of numbers between 0 and 1. So depending on what you mean with natural numbers no, there is no natural last number.
Actually, there is an infinite number of decimals between 0 and 1.
1.5
There is an infinite number of numbers between 1 and 2.
0.01 and 0.02
1.5, 1.7
1
A number can only contain 1 decimal.
0.1, 0.25 and 0.674 but note that there are thousands of decimals between 0 to 1.
When the fractional parts, if any, of the two decimal numbers sum to 1.
There are infinitely many fractions and decimals between 0 and 1.
the answer depends on what kind of numbers you are dealing with. If you are using only integers then there is no answer to this question. Integers are numbers without decimals, both negative, positive and zero. If you are using real numbers (which includes decimals), then then there are an infinite number of possibilities between 1 and 0 (ie. 0.1, 0.2, 0.3, 0.4, 0.5, 0.87, 0.6543 etc..).
