Rules
1. Shorten words
When speaking, you can shorten numbers 21 and above by dropping the word mươi.
Example:
- 21: hai mốt
- 32: ba hai
2. Numbers 21, 31, ..., 91
1 is pronounced as một in 01, 11 and combinations 01. However, in other 2-digit numbers from 21 to 91, it becomes mốt.
Example:
- 31 = 30 + 1 = ba mươi mốt.
- 41 = 40 + 1 = bốn mươi mốt.
3. Numbers 25, 35, ..., 95
It's the same for 5. 5 is pronounced as năm when it's 05 or in 05 combination.
In double digit numbers ending with 5 ( 15, 25, ..., to 95), it’s lăm.
Example:
- 35 = 30 + 5 = ba mươi lăm.
- 45 = 40 + 5 = bốn mươi lăm.
4. Numbers 24, 34, ..., 94.
In double digit numbers ending with 4 (24 to 94), except 14, we can use both bốn or tư.
In Southern Vietnamese, we usually use bốn more often.
