HELLO......FRIEND!!
THE ANSWER IS HERE,
a×b=b×a
Let a= -12/7 & b=-21/5
=> (-12/7)×(-21/5) = (-21/5)×(-12/7)
=> 36/5=36/5.
Hence, We can say that
a×b=b×a.
This property is also known as commutative property in multiplication.
:-)Hope it helps u.

Hi Friend !!!
==================
To Prove : a×b = b×a
a = -12/7
b = -21/5
-12/7 × -21/5 = -21/5 × -212/7
252/35 = 252/35
Hence proved
Hope it helps u:-)
