1. Trois cent trente: This is the standard and most common way.
2. Trois cent et trente: Adding "et" (and) is also grammatically correct, although less frequently used for numbers like this.
3. Trois-cent-trente: This is the same as the first option, just hyphenated, sometimes seen in written contexts requiring compactness.
4. Trois-cent trente: A slightly less common hyphenation style
5. (In a sentence with context suggesting approximation): "Environ trois cent trente" (approximately three hundred and thirty). This isn't a different way to *say* the number itself, but a way to use it in a sentence.
6. (In a list or table): 330 While not spoken, using the Arabic numeral is a perfectly valid way of representing the number in certain written forms.
The core of it remains "trois cent trente," with minor variations in writing style or contextual additions. French doesn't have multiple distinct wordings for a specific number like some languages might.
