You have already said it is 100 F for planet A.

Perhaps you mistyped the question.

It makes no sense physically to talk about one temperature being a certain fraction of another unless absolute (Kelvin or Rankine) temperatures are used. Such temperatures newer go below zero.

The Fahrenheit and Celsius scales do not measure absolute temperature, as you know.
