For checking Associative property we have to prove whether (frac211-frac311)-frac911 equal to frac211-(frac311-frac911)or not

L.H.S.

= (frac211-frac311)-frac911= (frac-111)-frac911= (frac-1011)

R.H.S.

= frac211-(frac311-frac911)= frac211-(frac-611)= frac811

L.H.S. ; ; not ; ; equal ; ; to ; ; R.H.S.

So,The associative property for is not true for subtraction of the rational numbers
