When we use words like first, second, third, fourth or 1st, 2nd, 3rd, 4th, in sentences, what will be the best way to write these? Also, what about numbers? Do we put them in words or as numerals?

Here are some sample sentences,

• He got first/1st class in that examination.
• He gave me two/2 books.
• He will be the first/1st to get there.
• My son is finishing his seventh/7th semester.
• The turkey weighed five/5 Kg.

Yes, I understand that we can have many examples like the above.

Do you think that you can give some general rules for these?
