Let's classify each of the given numbers in different mathematical categories:
-
-3
- Integer: Yes (it is a whole number)
- Rational Number: Yes (can be expressed as -3/1)
- Real Number: Yes (it exists on the number line)
- Negative Number: Yes (less than zero)
- Whole Number: No (not non-negative)
-
4.5
- Rational Number: Yes (can be expressed as 9/2)
- Real Number: Yes (it exists on the number line)
- Positive Number: Yes (greater than zero)
- Decimal: Yes (it is in decimal form)
- Not an Integer: No (it is not a whole number)
-
-4.89375872537653487287439843098... (a repeating decimal)
- Rational Number: No (it cannot be expressed as a fraction of two integers precisely due to the infinite decimal)
- Real Number: Yes (it exists on the number line)
- Negative Number: Yes (less than zero)
- Decimal: Yes (it is in decimal form)
-
-9.7654321
- Rational Number: Yes (can be expressed as -97654321/10000000)
- Real Number: Yes (it exists on the number line)
- Negative Number: Yes (less than zero)
- Decimal: Yes (it is in decimal form)
-
1
- Integer: Yes (it is a whole number)
- Rational Number: Yes (can be expressed as 1/1)
- Real Number: Yes (it exists on the number line)
- Positive Number: Yes (greater than zero)
- Whole Number: Yes (it is non-negative)
In summary, the classifications for each number are as follows:
- -3: Integer, Rational Number, Real Number, Negative Number
- 4.5: Rational Number, Real Number, Positive Number, Decimal
- -4.89375872537653487287439843098…: Real Number, Negative Number, Decimal (Not rational)
- -9.7654321: Rational Number, Real Number, Negative Number, Decimal
- 1: Integer, Rational Number, Real Number, Positive Number, Whole Number
