A number followed by the word percent is ______.

Explanation:
Percent expresses a number as a part per hundred, so the value carries no physical units. The percent sign just means divide by 100, turning the result into a pure number. For example, 40% equals 0.40, which has no units. So a number followed by percent is unitless. You can also think of it as a fraction (40/100) or a ratio (40 to 100), but in all cases the quantity is dimensionless.
