13.0

Answer "13" is a decimal value IF by "13" you mean 13 in our base-10 numbering system. In this system, the 3 in 13 stands for 3 units, and the 1 in 13 stands for 1 ten. Combining the 1 ten and the 3 units gives 10 + 3 = 13. We also say that 13 is a decimal value because it contains no nondecimal (non-base-10) fractional parts. You could write 13 as 13.0 if you wish. Whole numbers in our base-10/decimal system are always decimal values, by definition. Examples:

13 1/4 is not a decimal value; 13.25 is.

13 2/10 is a decimal value, actually, but not in a decimal representation.

13.2 means the same thing as 13 2/10, but in a decimal representation.

13 1/3 cannot be represented as a pure decimal; it equals 13.3333... (etc.)

"13" could be a number representation of a value in a number system other than base 10. For example, 13 is a value in the hexadecimal (base 16) number system. 13 hex = (1x16)+(3x1) = 19.
