To add these three numbers together, we first need to convert all the numbers to a common format.

-28 is already in the correct format, -28.
-3 8/10 can be converted to -3.8
-15 2/3 can be converted to -15.6667

Now we can add all the numbers together:
-28 + (-3.8) + (-15.6667) = -28 - 3.8 - 15.6667 = -47.4667

Therefore, the sum of -28, -3 8/10, and -15 2/3 is approximately -47.47.
