Step-by-step explanation:
The student has asked to determine if the number -33 is a whole number, integer, or rational number. The number -33 is an integer because it is a whole number without a fractional or decimal part, and negative numbers can also be integers. Additionally, -33 is a rational number because it can be expressed as a fraction −\(rac{33}{1}\), where both the numerator and denominator are integers and the denominator is not zero. However, it is not a whole number because whole numbers are non-negative and start from zero.
