Rank the size of a change in temperature of one degree Fahrenheit, one degree Celsius, and one kelvin. In other words, if a thermometer were to show that the temperature outside increased by these amounts, which change would feel the largest? If any of the options are the same magnitude, stack them above one another.

Rank the sizes of one degree in each scale from largest to smallest. To rank items as equivalent, overlap them.

Attempt:
1 degree Farenheit = 290.37 K
1 degree Celsius = 274.15 K
1 Kelvin = 1 K

How do I rank these?

They don't ask for size rankings, they ask for sizes of changes, and so you need to compute how big the numbers are all in one unit of measurement--I recommend Kelvins because they are the best--you already know that 1 degree change in Kelvin is the same as one degree change in Celsius, and the conversion factor from Fahrenheit is , so. . .

How would I go about with ranking them by sizes of change? I converted them to Kelvin, but I don't know how to place them in order of ranking (ie. Kelvin, Farenheit, Celsius, for instance, going from largest to smallest)

You know that 1 K = 1C in terms of change, and 1F = 5/9 K, so it's clearly K = C > F is the ranking.
