How 111 is written
111 is the sum of its place values, 100 + 10 + 1, and is written one hundred eleven.
Its ordinal form is one hundred eleventh — only the final element takes the ordinal ending — and on a check the amount line reads "One hundred eleven and 00/100", where 00/100 stands for zero cents.
The last part is not built from its digits: English names 10 to 19 with single irregular words, so this is eleven, never ten one.
