Answer:
B, C, A, D (in order from top to bottom)
Explanation:
An "opposite" in mathematical terms would be a positive number and a negative number. They are the exact same distance from each other, like on a number line.
An example of opposites would be -1 and 1, where one is negative and one is positive, but they both have the same number.
The term 3.2 would have the opposite of -3.2, and so on.
3.2 ⇒ B. -3.2
-2.3 ⇒ C. 2.3
-1.5 ⇒ A. 1.5
5.1 ⇒ D. -5.1
