I couldn't understand your question, but I can give you the definition of an additive inverse. Additive Inverse is an opposite of a sign like +\- or -/+
For division the additive inverse is multiplication. Your question said inte so i assumed that means integer, so the additive inverse of an integer is the negative and the positive signs like -1/1 or 1/-1 :)
The largest of the three would be 53, then 51, then 49.
11 x < - 66
x < - 66 / 11
x < - 6
hope this helps!
