What property represents a rational number added to a rational number gives a rational number answer?
The relevant property is the closure of the set of rational numbers under the operation of addition.
Why does a rational number plus a rational number or a rational number multiplied by a rational number equal to rational number?
The way in which the binary functions, addition and multiplication, are defined on the set of rational numbers ensures that the set is closed under these two operations.
Which number produces a rational number when added to 0.5?
Since the set of rational numbers is closed under addition, any rational number added to 0.5 will total another rational number.
Is Under root 8 is a real number?
is under root 8 is a rational number
Is a rational number closed under addition?
No. A number cannot be closed under addition: only a set can be closed. The set of rational numbers is closed under addition.
Is 7 rational or irrational?
7 is a rational number because whole numbers, integers, and natural numbers fit under rational and 7 is a natural number:)Yes.
Are rational number commutative under subtraction and division?
No.
Why is division not closed for rational numbers give an example?
If a set is closed under an operation. then the answer will be a part of that set. If you add, subtract or multiply any two rational numbers you get another national number. But when it comes to division, it is closed except for one number and that is ZERO. eg 3.56 (rational number) ÷ 0 = no answer. Since no answer is not a rational number, that rational numbers are not closed under the operation of division.
Are rational numbers closed under multiplication?
Rational numbers are closed under multiplication, because if you multiply any rational number you will get a pattern. Rational numbers also have a pattern or terminatge, which is good to keep in mind.
Is the set of rational numbers closed under division and Why?
No. Zero is a rational number, but division by zero is not defined.
Is rational number is a cyclic group under addition?
No Q is not cyclic under addition.
Can you add two rational numbers and get an irrational number?
No. The set of rational numbers is closed under addition (and multiplication).
