2. What are associative property and commutative property of rational numbers?
Some of the properties of rational numbers are:
Associative Property: When it comes to addition and multiplication, rational numbers follow the Associative Property. Assuming x, y, and z are three rational numbers, x+(y+z)=(x+y)+z for addition.
x(yz)=(xy)z is used for multiplication.
For example, 1/3 + (1/4 + 3/3) equals (1/3+ 1/4) + 3/3.
= 19/12 =19/12
Commutative Property: The addition and multiplication of two rational integers, x and y, are always commutative. The commutative property does not apply to subtraction. Examine the solved cases to obtain a better understanding of this attribute.
Ex: 1/3+2/3 = 3/3 Commutative Law of Addition: x+y = y+x
3. What is distributive property and closure property?
Some of the properties of distributive property and closure property.
Distributive Property: Consider the three rational numbers x, y, and z: x. (y+z) = (x. y) + (x. y) + (x. y) + (x. y) + (x. y) + (x. y) + (x. y) + (x . z). We'll provide an example to demonstrate the property.
(1/3.1/4)+(1/3.2/5) = 1/3.(1/4+2/5)
1/12+2/10 = 1/3.(17/20)
=17/60=17/60
As a result, L.H.S = R.H.S.
Closure Property: Closure Property: When two rational numbers, x and y, are added, subtracted, and multiplied, the outcome is always a rational number. As division by zero isn't specified, the Closure Property is not relevant. To put it another way, we can state that the closure property applies to divisions other than zero.
26/21 = 4/7 + 2/3
6/12 = 4/3 – 2/4
2/3 = 6/15 = 3/5
