How 120 is written

120 is the sum of its place values, 100 + 20, and is written one hundred twenty.

Its ordinal form is one hundred twentieth — only the final element takes the ordinal ending — and on a check the amount line reads "One hundred twenty and 00/100", where 00/100 stands for zero cents.

British English inserts "and" before the last part, giving one hundred and twenty, where American English writes one hundred twenty without it.
