To simplify \(-100/5\):
\[ -100 \div 5 = -20 \]
Now, let's determine the classification of the number \(-20\):
- Real: All numbers are real numbers, including integers, rational numbers, and irrational numbers. So \(-20\) is real.
- Rational: Any number that can be expressed as a fraction of two integers is rational. Since \(-20\) can be written as \(-20/1\), it is considered a rational number.
- Integer: Whole numbers and their negatives fall under integers. \(-20\) is an integer.
- Whole number: Whole numbers are non-negative integers (0, 1, 2, ...). Since \(-20\) is negative, it is not a whole number.
Based on this classification, the correct set of numbers that includes the simplified value of \(-100/5\) is:
Real, Rational, Integer
