Answer: -2, |-4/5|, |-1|, |3.5|, |-4.2| (option A)
Explanation:
Absolute value bars make all numbers the positive version of themselves, so you can make |-4.2| into 4.2, |-4/5| into 4/5, and so on.
Once you do that, you just order 4.2, 4/5 (which is also 0.8), 1, -2, and 3.5 in order to get:
-2, 4/5, 1, 3.5, 4.2
Finally, you choose the option that contains those numbers in order with the absolute value bars added. That is how you get A as the answer.
I hope this helps!
