The Attempt at a Solution

I don't know how to do this problem... but Celsius degree results from a change in temperature which can be converted to kelvin...
so C^(degrees) = K

If you are talking just about the two temperature scales (Kelvin and Celsius), then there is a simple relation between them, and what you have shown is not it.

given 10 degrees as the final temp. and 5 degrees as the initial temp.
both C degrees and K have the formula Tf - Ti;
1/(K) = 1/(C degrees)
1/(tf - ti) = 1/(tf - ti)
1/5 = 1/5
