Question

Can you give me some property sums of rational no.class 8

Answer 1

properties of addition of rational numbers i.e. closure property, commutative property, associative property, existence of additive identity property and existence of additive inverse property of addition of rational numbers.

Closure property of addition of rational numbers: 

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. 

For example:

(i) Consider the rational numbers 1/3 and 3/4 Then, 

(1/3 + 3/4) 

= (4 + 9)/12

= 13/12, is a rational number 

I hope this will help you
