Answer:
a) -15, -8, -3.3, 8/9
Step-by-step explanation:
b) 8/9, -3.3(And I say its -3.3, because you need to write it in its original form.), so far its 8/9, -3.3, -8, -15.
c) Because the absolute value is the positive value of that number. (i.e, -3 is 3 places away from 0, so it's absolute value would be 3.)
