The expression \( 19 - 3 \) results in \( 16 \).
- \( 16 \) is a whole number.
- \( 16 \) is also an integer.
- \( 16 \) can be expressed as a fraction (e.g., \( \frac{16}{1} \)), so it is a rational number.
- However, \( 16 \) is not an irrational number since irrational numbers cannot be expressed as a fraction of two integers.
Since the question asks for the type of number that results from the expression, the correct answers would include "a whole number," "an integer," and "a rational number."
However, if you have to choose one option, the most general and correct answer is:
an integer.
