(-2 5/11) + (-1 2/11) - 7/11

First, add the numbers in the parentheses:
= (-2 - 1) + (5/11 - 2/11) - 7/11
= -3 + 3/11 - 7/11
= -3 - 4/11
= -3 4/11

(-4 1/16) - 2 3/4 + 1 1/8

First, subtract the numbers in the parentheses:
= (-4 - 2 + 1) + (1/16 - 3/4 + 1/8)
= -5 + (-9/16)
= -5 - 9/16
= -5 9/16

Therefore, the solutions are:

(-2 5/11) + (-1 2/11) - 7/11 = -3 4/11(-4 1/16) - 2 3/4 + 1 1/8 = -5 9/16
