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?

Your question doesn't really make sense. You've set ice density as a constant by saying that it takes up 92% of it's original volume as water. If the density is assumed to be constant, than the relationship between x and y are constant.
Now, if z changes (which means that the ice caps are melting) then that would produce a corresponding equal change in both x and y. So any change in z would affect the earth's water level, which is what I assume you referred to when you said that "no change occurs".
x+y=z
y=ax
.:(a+1)x = z or (1+1/a)y = z

Unfortunately, much of the icecap is not floating - it's in Greenland and Antarctica. There's no displacement when those icecaps melt and the seas must rise.

it looses 8% of its volume in transition from ice to liquid so everything below would have to decrease 12.5% per100%of amount above water z=100% y=80% x=20% with a loss factor of 8% . 100 divided by 8 = 12.5 so 12.5 times x%

I have to agree with Samantha...and my IQ is only 146!
