Math Problem Statement
For each number below, select which set(s) of numbers it belongs to. Select all that apply.
a) 0 0
Counting Numbers
Integers
Rational Numbers
Irrational Numbers
Real Numbers
Solution
Let's go through each of the sets and determine if the number belongs to them:
-
Counting Numbers: Counting numbers (also known as natural numbers) typically start from 1 and go upwards (1, 2, 3, ...). Some definitions include 0 in the set of natural numbers, but traditionally, counting numbers do not include 0.
- 0 is not in the set of Counting Numbers.
-
Integers: Integers include all whole numbers, both positive and negative, as well as zero (..., -2, -1, 0, 1, 2, ...).
- 0 is in the set of Integers.
-
Rational Numbers: Rational numbers are numbers that can be expressed as the quotient or fraction of two integers, where the denominator is not zero. can be expressed as .
- 0 is in the set of Rational Numbers.
-
Irrational Numbers: Irrational numbers cannot be expressed as a simple fraction; they have non-repeating, non-terminating decimal expansions. Examples include and .
- 0 is not in the set of Irrational Numbers.
-
Real Numbers: Real numbers include both rational and irrational numbers, encompassing all possible numbers along the number line.
- 0 is in the set of Real Numbers.
Summary
The number belongs to the following sets:
- Integers
- Rational Numbers
- Real Numbers
