Question

Give an example to show that subtraction is not a associative for national number

Answer 1

Step-by-step explanation:

According to associative property of subtraction

(A-B)-C=A-(B-C)

Let us take A=3/7,B=6/7,C=5/7

Left Hand Side

(3/7-6/7)-5/7

-3/7-5/7

-8/7

Right Hand Side

3/7-(6/7-5/7)

3/7-1/7

2/7

Left Hand Side is not equal to Right Hand Side

Hence,Subtraction is not an associative property for rational number
