1 th: Any number that ends in 4, 5, 6, 7, 8, 9 or 0 (apart from 0 itself) has an ordinal form ending in "-th" (in this case, "fourth"). When written using digits, we write the digit(s) and add "-th" to the end of it. Other examples: 5th, 20th, 77th.
2 rd: All ordinal numbers that end in 3 take the ending "-rd", which represents the end of the word "third" (in this case, "forty-third"). Exception: the number 13 (thirteen) and large numbers ending in 13 take the ending "-th" (the end of the word "thirteenth"). Examples: 23rd (twenty-third), 53rd (fifty-third), 213th (two hundred and thirteenth).
3 th: Any number that ends in 4, 5, 6, 7, 8, 9 or 0 (apart from 0 itself) has an ordinal form ending in "-th" (in this case, "forty-fifth"). When written using digits, we write the digit(s) and add "-th" to the end of it. Other examples: 6th, 70th, 99th.
4 nd: All ordinal numbers that end in 2 take the ending "-nd", which represents the end of the word "second" (in this case, "one hundred and thirty-second"). Exception: the number 12 (twelve) and large numbers ending in 12 take the ending "-th" (the end of the word "twelfth"). Examples: 62nd (sixty-second), 222nd (two hundred and twenty-second), 112th (one hundred and twelfth).

1 st: All ordinal numbers that end in 1 take the ending "-st", which represents the end of the word "first" (in this case, "twenty-first"). Exception: the number 11 (eleven) and large numbers ending in 11 take the ending "-th" (the end of the word "eleventh"). Examples: 41st (forty-first), 201st (two hundred and first), 111th (one hundred and eleventh).
2 th: Any number that ends in 4, 5, 6, 7, 8, 9 or 0 (apart from 0 itself) has an ordinal form ending in "-th" (in this case, "tenth"). When written using digits, we write the digit(s) and add "-th" to the end of it. Other examples: 6th, 80th, 108th.
3 th: 11 is written "eleven", and the ordinal form of this number is "eleventh". We therefore use the ending "-th" here. This ending is used for all of the numbers from 10 to 19.

1 thirteenth: To form the ordinal version of most numbers, we simply add the ending "-th". This is the case with 13 (thirteen), which becomes "thirteenth". Other examples: 11 (eleven) -> eleventh; 77 (seventy-seven) -> seventy-seventh.
2 third: All ordinal numbers that end in 3 take the ending "-rd", which represents the end of the word "third". Exception: the number 13 (thirteen) and large numbers ending in 13 take the ending "-th". Examples: 23rd (twenty-third), 53rd (fifty-third), 213th (two hundred and thirteenth).

So tell me, Jee-Zay, what’s your [not done] ninety-ninth 3 problem?
1 first: The ordinal number corresponding to the number 1 (one) has an irregular form, and is written "first". The ending "-st" is therefore used for most ordinal numbers ending in 1 (with the exception of 11 or other numbers ending in 11). For example: 21st = twenty-first, 101st = (one) hundred and first, 211th = two hundred and eleventh.
2 fiftieth: To write the ordinal form of two-digit numbers ending in 0, we take the cardinal number (fifty), remove the "-y" (fift), and add the ending "-ieth" (fiftieth). Another examples: 30 -> thirty -> thirt -> thirtieth.
3 ninety-ninth: To write the ordinal form of numbers ending in 9 (nine), we remove the "-e" before adding the standard "-th" ending. Another examples: 49 -> forty-nine -> forty-nin -> forty-ninth.

1 sixty-fourth: To form the ordinal version of the number sixty-four (64), we simply add the standard ending "-th". Other similar examples: 55 -> fifty-fifth, 86 -> eighty-sixth.
2 two hundredth: To form the ordinal version of multiples of 100, we simply add the ending "-th". For example: 100th = one hundredth, 700th = seven hundredth.
3 seven hundred twenty-third: To form the ordinal version of long numbers, we only apply an ordinal ending to the last part of the number (in this case, 23 = twenty-third). Numbers ending in 3 end in "third" rather than "-th" (apart from 13). Note that in UK English, we would add "and" after "hundred": "seven hundred and twenty-third".
