Frequently asked questions
How do you write 21 in words?
Twenty-one.
How do you write 21 on a check?
Twenty-one and 00/100 dollars.
Do you hyphenate numbers in words?
Yes. Compound numbers from twenty-one to ninety-nine take a hyphen: forty-two, seventy-five. Other parts are separate words: one hundred five, three thousand.
Should I write "and" in numbers?
In American English, "and" is usually left out of whole numbers (one hundred five) and reserved for the decimal point on checks ("and 50/100"). In British English "and" goes before the last two digits: one hundred and five.
How do you write a number on a check?
Write the dollars in words, then "and", then the cents as a fraction of 100: $1,250.50 is "One thousand two hundred fifty and 50/100 dollars". Draw a line after the words so nothing can be added.
