Formal:
* Tatlong daan at isa (pronounced: tat-long da-an at ee-sa) - This is the most literal and formal way to say it.
Informal:
* Tres-o-uno (pronounced: tres-o-oo-no) - This is a more casual and commonly used way to say it, using Spanish numbers.
Other Options:
* Tatlo-isang daan (pronounced: tat-lo-ee-sang da-an) - This is another way to say it, meaning "three-one hundred."
The best option depends on the context and who you are talking to. If you are talking to someone formally, it is best to use the formal "Tatlong daan at isa." If you are talking to someone informally, you can use "Tres-o-uno."
