Answer: Step-by-step explanation: The difference of 20.39 and 7.6 is like subtracting 20.39 - 7.6. Or, taking 7.6 away from 20.39.
When we subtract 20.39 - 7.6 we get 12.79 as our answer.
For example, if we had $20.39 and we spent $7.60, we would have $12.79 left to spend on something else because $20.39 - $7.60 = $12.79.
