The closure property of rational numbers states that when any two rational numbers are added, subtracted, or multiplied, the result of all three cases will also be a rational number.
Irrational numbers are not closed under addition, subtraction, multiplication, and division.
The closure property states that if a set of numbers (integers, real numbers, etc.) is closed under some operation (such as addition, subtraction, or multiplication, etc.), then performing that operation on any two numbers in the set results in the element belonging to the set.
Closure property means when you perform an operation on any two numbers in a set, the result is another number in the same set or in simple words the set of numbers is closed for that operation.
The associative property of multiplication can be understood with the help of an example. Let us multiply any three numbers (4 × 6) × 10, we get the product as 24 × 10 = 240. Let us group these numbers as 4 × (6 × 10), we still get the product as 4 × 60 = 240.
Answer: We can say that rational numbers are closed under addition, subtraction and multiplication. For rational numbers, addition and multiplication are commutative.
Closure Property Examples Add-15 + 2 = -13Sum is an integer Subtract -15 - 2 = -17 Difference is an integer Multiply -15 x 2= -30 Product is an integer Divide -15 / 2 = -7.5 Quotient is not an integer
The Closure Property: The closure property of a whole number says that when we add two Whole Numbers, the result will always be a whole number. For example, 3 + 4 = 7 (whole number).
Closure property of rational numbers under subtraction: The difference between any two rational numbers will always be a rational number, i.e. if a and b are any two rational numbers, a – b will be a rational number.
Answer: So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number. Rationals are closed under addition (subtraction).
