  8. 53rd: Fifty-third

  9. 41st: Forty-first

  10. 28th: Twenty-eighth

  11. 82nd: Eighty-second

  12. 39th: Thirty-ninth

  13. 16th: Sixteenth

  14. 14th: Fourteenth

  15. 25th: Twenty-fifth

When writing ordinal numbers, it is common to use a combination of numbers and letter suffixes: -st, -nd, -rd, and -th. For example, 1 becomes 1st, 2 becomes 2nd, 3 becomes 3rd, and the suffix -th is used for all other numbers.
