b) -3.5, 3.5, 3.5

c) 5 1/2, -5 1/2, 5 1/2

Explanation:

The opposite number of a value is the number that adds to it to make zero. To find the opposite of a number you need to switch the sign, either from positive to negative or vice versa. The absolute value of a number is the distance from zero it is. Since distance cannot be negative you just need to take the number and make it positive.
