When ice melts it takes up 92% of its original volume as water. Let x% of Earth's total floating icecap volume be above water, and let y% be below water. Earth's floating icecap volume is z% of Earth's total icecap volume. If z>0, by what percent must y decrease in terms of x and z so that no change occurs if Earth's icecaps melt?

Not really that hard. If ice is floating then it is already displacing the same amount of water as it contains. The fact that it is floating is sufficient to prove that. Its relative density doesn't really matter, the less dense the more of it sticks above the water. But when it melts the level doesn't change.
Only ice which is not floating can change the water level. As I understand it that is not happening.
