Answer:
a fraction like 1/2 and its opposite -1/2
Step-by-step explanation:
By definition two numbers are opposite if their distance to 0 is the same.
distance to 0 for 1/2 = 1/2 - 0 = 1/2
distance to 0 for -1/2 = 0 - (-1/2) = 1/2
since both have the same distance, they are opposite with each other
Another way to verify it , is that the sum of the 2 values should be 0. in our case,
1/2 + (-1/2) = 1/2 - 1/2 = 0
