The Brainliest Answer!

given, a= -3/4 and b = 4/9

verification : ab = ba

-3/4(4/9) = 4/9(-3/4)

⇒-12/36 = -12/36

⇒-1/3 = -1/3

here , proved ab = ba

hence commutative property under multiplication proved

so we have the given numbers a= -3/4 and b=4/9 and we have to check whether this property holds or not in multiplication.

so in L.H.S= a*b

= -3/4 *4/9

= -12/36= -1/3

in R.H.S = b*a

= 4/9* -3/4

=-12/36= -1/3

as -1/3= -1/3

∴ L.H.S= R.H.S verified..
