They sound almost the same. There is no single rule, but a few clues settle most words.
Try a little practice ↓THE RULES, ONE AT A TIME
An -ation word in the same family often means -ant and -ance.
toleration → tolerant, tolerance; observation → observantA soft c or g (or qu) just before the ending points to -ent and -ence.
decent; urgent; frequentIf a related word has a clear e sound there, use -ent.
residential → resident; presidential → president-ant goes with -ance, and -ent goes with -ence.
distant → distance; patient → patienceAfter a hard c or g, it is -ant: significant, elegant. Many common words follow no clue and just need learning: assistant, relevant, excellent, dependent, independent. The -ation clue has exceptions too: presentation → present. British English also separates dependant (a person, noun) from dependent (adjective).
