Convert -1 1/4 to the mixed number -5/4.

Then the product of -1 1/4 and -2/5 is   (-5/4)(-2/5) = 10/20, or 1/2.

Please, do not use " x " to indicate multiplication.  " x " is reserved for naming variables.  Instead, use " * " to indicate mult.

Thus, your problem is best written    -1 1/4  *  -2/5
