Explanation:

Step1: Subtract the absolute values

First, we consider the absolute values of the two numbers. The absolute value of -51.25 is 51.25, and the absolute value of 39.50 is 39.50. We subtract the smaller absolute value from the larger one: $51.25 - 39.50 = 11.75$.

Step2: Determine the sign

Since the number with the larger absolute value is -51.25 (negative), the result will be negative. So we have $-51.25 + 39.50 = -11.75$.

Answer:

-11.75
