Which set of numbers does -55 belon?
natural
whole
integers
irrational
i'm not sure but leaning towards natural or whole. Can someone please help?
whole numbers or naturals do not contain negatives, so
integers
To determine which set of numbers -55 belongs to, let's go through each set and see if it fits the definition.
1. Natural Numbers: The set of natural numbers includes positive integers starting from 1 (1, 2, 3, 4, ...). Since -55 is not a positive integer, it does not belong to the set of natural numbers.
2. Whole Numbers: The set of whole numbers includes zero and all positive integers (0, 1, 2, 3, ...). Although -55 is not a positive integer, it is an integer, and therefore it does belong to the set of whole numbers.
3. Integers: The set of integers includes both positive and negative whole numbers, including zero (-∞, ..., -3, -2, -1, 0, 1, 2, 3, ..., +∞). As -55 is a negative whole number, it does belong to the set of integers.
4. Irrational Numbers: Irrational numbers are numbers that cannot be expressed as fractions or terminating decimals. -55 is a rational number and can be expressed as the fraction -55/1 or as the decimal -55.0. Therefore, it does not belong to the set of irrational numbers.
Based on this analysis, -55 belongs to the set of whole numbers and to the set of integers.
