The closure property of addition states that when any two elements of a set are added, their sum will also be present in that set. The closure property formula for addition for a given set S is: ∀ a, b ∈ S ⇒ a + b ∈ S.
Here, the given number, √2 cannot be expressed in the form of p/q. Alternatively, 2 is a prime number or rational number. Here, the given number √2 is equal to 1.4121 which gives the result of non terminating and non recurring decimal, and cannot be expressed as fraction .., so √2 is Irrational Number.
Some of the examples of rational numbers are 1/2, 1/5, 3/4, and so on. The number “0” is also a rational number, as we can represent it in many forms such as 0/1, 0/2, 0/3, etc.
Closure property We can say that rational numbers are closed under addition, subtraction and multiplication. For example: (7/6)+(2/5) = 47/30. (5/6) – (1/3) = 1/2.
Irrational numbers are not closed under addition, subtraction, multiplication, and division.
0.7777777 is a rational number with recurring decimals.
The closure property of addition states that when any two elements of a set are added, their sum will also be present in that set. The closure property formula for addition for a given set S is: ∀ a, b ∈ S ⇒ a + b ∈ S.
Answer and Explanation: The number 3.14 is a rational number. A rational number is a number that can be written as a fraction, a / b, where a and b are integers. The number pi is an irrational number. An irrational number is a number that is not rational, and cannot be written as a fraction.
Example:5/9 + 7/9 = 12/9 is a rational number. Closure Property of Subtraction: The sum of two rational numbers is always a rational number. If a/b and c/d are any two rational numbers, then (a/b) – (c/d) = is also a rational number. Example: 7/9 – 5/9 = 2/9 is a rational number.
