Properties of rational numbers
Closure property: For two rational numbers say x and y the results of addition, subtraction and multiplication operations gives a rational number. We can say that rational numbers are closed under addition, subtraction and multiplication.
Do you know why division is not under closure property?
Division is not under closure property because division by zero is not defined. We can also say that except ‘0’ all numbers are closed under division.
Commutative law: For rational numbers, addition and multiplication are commutative.
Commutative law of addition: a+b = b+a
Commutative law of multiplication: a×b = b×a
Subtraction is not a commutative property i. e. a-b ≠ b-a.
Associative law: Rational numbers follow the associative property for addition and multiplication.
Suppose x, y and z are rational then for addition: x+(y+z)=(x+y)+z
For multiplication: x(yz)=(xy)z.
Some important properties that should be remembered are:
0 is an additive identity and 1 is a multiplicative identity for rational numbers.For a rational number x/y IS the additive inverse of x/y....
hope it helps u.
