How it works
English numbers are read in groups of three digits — ones, thousands, millions and so on. Each group is spoken as hundreds, tens and units, compound numbers from twenty-one to ninety-nine take a hyphen, and in American usage the word “and” is saved for the decimal point. On a check, the cents follow as a fraction over 100.
