Step-by-step explanation:
The question involves mixed fractions. Mixed fractions are first converted into proper fractions and then any operation can be performed on them.

Answer:
4 and 8
Step-by-step explanation:
Let 'a' represent one of the numbers. Then the other is 12-a, and their difference is ...
a - (12-a) = -4
2a = 8 . . . . add 12
a = 4 . . . . . divide by 2
12-a = 8 . . . . find the other number
The two numbers are 4 and 8.
