Question

Micah and Joel each have a set of five rational numbers. Although their sets are not the same, their sets of numbers have absolute values that are the same.


Show an example of what Micah and Joel could have for numbers. Give the sets in order and the absolute values in order.

Answer 1

Answer:

You can build the two sets using the same numbers, but alternating the signs  

So that every element of A is different from every element of B, but if you apply the absolute values all numbers become positive, and the two sets become identical.
