Write predicates One converts centigrade temperatures to Fahrenheit, the other checks if a temperature is below freezing.
F = C * 9 / 5 + 32
Rule
Centigrade to Fahrenheit (c_to_f)F is C * 9 / 5 + 32
Program-
c_to_f(C,F) :-F is C * 9 / 5 + 32.
% here freezing point is less than 32 Fahrenheit
freezing (F) :-F =< 32.
