To add -1 3/10 and -4 2/15, we first need to convert the mixed numbers to improper fractions:
-1 3/10 = -13/10
-4 2/15 = -62/15

Next, we add the fractions:
-13/10 + (-62/15) = -195/30 + (-124/30) = -319/30

So, the sum of -1 3/10 and -4 2/15 is -319/30.

Therefore, the correct answer is not listed in the given responses.
