Question

check the associativity for addition 2/5, 1/9,2/5​

Answer 1

Step-by-step explanation:

Given rational numbers are 2/5 ,1/9 ,2/5

Associate property:-

If a,b and c are three rational numbers then (a+b)+c=a+(b+c) is called associative property under addition in rational numbers.

Now ,

(2/5+1/9)+2/5

=>(18+5)/45+(2/5)

=>23/45+2/5

=>(23+18)/45

=>41/45....(1)

and

2/5+(1/9+2/5)

=>2/5+(23/45)

=>(18+23)/45

=>41/45.....(2)

from (1) and (2) associative property under addition in rational numbers holds good
