Answer:
I'm not sure what the point of this exercise is. I am confused because I see that the number 12 is written in letters instead as a number, and I see that the number 25 is written with words and hyphenated correctly.
Explanation:
The rules for writing numbers are this:
1. For the numbers 1 - 9, the word should be written as words: one, two , three, ....
2. For numbers greater than nine, typically you should use numbers: 10, 11, 12 ....
3. If you do write a number with words above 20, the words must be hyphenated: twenty-one, twenty-two, ....
