The task involves converting ordinal numbers (e.g., 33rd, 24th) into their corresponding word forms. Here's how to solve the problem step by step:
Steps to Solve:
1.
Understand Ordinal Numbers: Ordinal numbers indicate position or rank (e.g., first, second, third).
2.
Identify Patterns: Familiarize yourself with common ordinal number patterns (e.g., -st for 1st, -nd for 2nd, -rd for 3rd, and -th for most other numbers).
3.
Write the Word Forms: Convert each given ordinal number into its word form.
Solution:
Here are the word forms for each ordinal number:
| Ordinal Number | Word Form |
|-----------------|------------------|
| 33rd | thirty-third |
| 24th | twenty-fourth |
| 63rd | sixty-third |
| 55th | fifty-fifth |
| 99th | ninety-ninth |
| 75th | seventy-fifth |
| 73rd | seventy-third |
| 29th | twenty-ninth |
| 34th | thirty-fourth |
| 10th | tenth |
| 25th | twenty-fifth |
| 40th | fortieth |
| 100th | hundredth |
| 35th | thirty-fifth |
| 6th | sixth |
| 21st | twenty-first |
| 13th | thirteenth |
| 87th | eighty-seventh |
| 51st | fifty-first |
| 32nd | thirty-second |
| 7th | seventh |
| 1st | first |
Explanation:
-
Single-Digit Ordinals:
- 1st → first
- 2nd → second
- 3rd → third
- 4th → fourth
- 5th → fifth
- 6th → sixth
- 7th → seventh
- 8th → eighth
- 9th → ninth
-
Double-Digit Ordinals:
- For numbers ending in 1 (except 11), use "-first" (e.g., 21st → twenty-first).
- For numbers ending in 2 (except 12), use "-second" (e.g., 32nd → thirty-second).
- For numbers ending in 3 (except 13), use "-third" (e.g., 43rd → forty-third).
- For all other numbers, use "-th" (e.g., 24th → twenty-fourth).
-
Special Cases:
- Numbers like 11th, 12th, and 13th always end in "-th" (e.g., eleventh, twelfth, thirteenth).
Final Answer:
\[
\boxed{
\begin{array}{ll}
33rd & \text{thirty-third} \\
24th & \text{twenty-fourth} \\
63rd & \text{sixty-third} \\
55th & \text{fifty-fifth} \\
99th & \text{ninety-ninth} \\
75th & \text{seventy-fifth} \\
73rd & \text{seventy-third} \\
29th & \text{twenty-ninth} \\
34th & \text{thirty-fourth} \\
10th & \text{tenth} \\
25th & \text{twenty-fifth} \\
40th & \text{fortieth} \\
100th & \text{hundredth} \\
35th & \text{thirty-fifth} \\
6th & \text{sixth} \\
21st & \text{twenty-first} \\
13th & \text{thirteenth} \\
87th & \text{eighty-seventh} \\
51st & \text{fifty-first} \\
32nd & \text{thirty-second} \\
7th & \text{seventh} \\
1st & \text{first} \\
\end{array}
