-12m • 2/3n is your problem (note replacement of the cross symbol by a fat 'multiply dot' because in Algebra we prefer to reserve x to be the name of an unknown variable)
since two thirds of -12 is -8, the answer is -8mn ... ASSUMING that second original factor was "two thirds of n"--which it should be, according to PEMDAS. (If you intended a denominator to be 3n, it would have had to have been parenthesized.)
