what is -1/3 plus (-3/11)

To add fractions, you need to find a common denominator. In this case, the common denominator is 33 (the least common multiple of 3 and 11).

-1/3 can be written as (-1/3) * (11/11) = -11/33

(-3/11) can be written as (-3/11) * (3/3) = -9/33

Now, you can add the two fractions: -11/33 + (-9/33) = (-11-9)/33 = -20/33.

Therefore, -1/3 plus (-3/11) equals -20/33.
