Answer: A -22 can be a rational number as well as a integer
Step-by-step explanation:
Whole Number: A whole number is not a fraction or a decimal so a example would be: 43 or 85 or 1 or 3. Zero is not a whole number. Negative are not whole numbers
Rational number: A rational number is a number that can be expressed as a fraction or a decimal. Like 33 can be 33/1. Most numbers are rational. Zero is a rational number.
Integers: A integer is not a fraction or a decimal. its a positive or negative number. Example: 1 or -5 or 85 or -445. there is still some arguments about if zero is a integer.
Irrational numbers: A irrational number cannot be expressed as a ratio. So for example pi: 3.141592653589......(it keeps on going, we haven't even gotten to the end because its infinite).
Natural numbers: Natural numbers are positive numbers. Example: 1,6,3,4,62,3 etc. Sometimes zero is a natural number.
