Question

Verify the property x + y = y + x of rational number by taking X = -⅔ and y = -⅚

Answer 1

x + y = y + x

x = -2/3 & y = -5/6

(-2/3) + (-5/6) = (-5/6) + (-2/3)

Now, Without actual calculation if we transpose the number -2/3 to LHS and -5/6 to RHS then,

(-2/3) + (2/3) = (-5/6) + (5/6)

0 = 0

LHS = RHS

Hence, Verified
