Question

give an example to show that commutative property does not hold good for subtraction of rational number​

Answer 1

Answer:

Subtraction of two rational numbers is not commutative. Therefore, Commutative property is not true for subtraction.

Answer 2

Ok it’s not commutative for rational numbers we know that but why?

Here’s an example—

If we subtract 3/5 from 4/5 we get 1/5 as the answer.

But same if if we do it opposite way—

4/5 subtracted from 3/5 we get -1/5 which is an integer and not a rational number.

So hence the rule of commutativity is false under subtraction of rational numbers.
