Answer:
The number that both a rational number and a whole number is 22
Step-by-step explanation:
The whole numbers are the non-negative integers
- Whole numbers ∈ the set of Integers
- Whole numbers ∈ the set of Rational numbers
The integers are rational numbers with denominators 1
- Integers ∈ the set of Rational numbers
The rational numbers are the numbers that can be written in the form of [tex]\frac{a}{b}[/tex] ,
b ≠ 0
Let us study the numbers in the figure:
The set of whole numbers ⊂ the set of integers ⊂ the set of rational numbers
∵ 22 ∈ the set of whole numbers
∴ 22 is a whole number
∴ 22 is a whole number and an integer
∴ 22 is a whole number, an integer, and a rational number
The set of integers ⊂ the set of rational
∵ -88 and -191 ∈ the set of integers
∴ -88 and -191 are integers
∴ -88 and -191 are integers and rational numbers
∵ -10.1 ∈ The set of rational numbers
∴ -10.1 is a rational number
Let us answer the question
→ We need to find a number that is a rational number and a whole number,
which means it must ∈ to the set of the whole numbers
∵ We only have one number ∈ the set of whole numbers, it is 22
∴ The number that both a rational number and a whole number is 22
