Let's solve the problem step by step.
---
A) Write the ordinal numbers.
We are given ordinal number words and need to write them as numerals (e.g., "first" → "1st").
1)
thirteenth → 13th
2)
seventh → 7th
3)
nineteenth → 19th
4)
first → 1st
5)
twenty-fifth → 25th
---
B) Write the ordinal numbers in words.
Now, we convert the numerals with suffixes into their word forms.
1)
16th → sixteenth
2)
4th → fourth
3)
22nd → twenty-second
4)
10th → tenth
5)
28th → twenty-eighth

🔍 Explanation:
- Ordinal numbers indicate position or order (e.g., 1st, 2nd, 3rd).
- The suffixes change based on the number:
- Most numbers use
-th (e.g., 4th, 10th, 13th).
- Exceptions:
- 1st (first), 2nd (second), 3rd (third)
- Numbers ending in 1 (except 11): use
-st (e.g., 21st = twenty-first)
- Numbers ending in 2 (except 12): use
-nd (e.g., 22nd = twenty-second)
- Numbers ending in 3 (except 13): use
-rd (e.g., 23rd = twenty-third)
- All others use
-th
This pattern helps us correctly write ordinals in both numeral and word form.
