\r\n Rules for Writing 21 in Words Correctly\r\n <\/h2>\r\n\r\n
\r\n

\r\n 1. Always Use a Hyphen\r\n <\/h3>\r\n

\r\n Standard English usage requires a hyphen in compound numbers from twenty-one to ninety-nine that do not end in zero. For example, write twenty-one<\/strong>, thirty-two<\/strong>, and ninety-nine<\/strong>. In formal writing, avoid writing \u201ctwenty one\u201d without a hyphen.\r\n <\/p>\r\n <\/div>\r\n\r\n

\r\n

\r\n 2. Follow Capitalization Rules\r\n <\/h3>\r\n

\r\n Use lowercase letters when the number appears within a sentence: twenty-one<\/strong>. Capitalize the first letter when it begins a sentence or follows the capitalization style of a title: Twenty-One<\/strong>.\r\n <\/p>\r\n <\/div>\r\n\r\n

\r\n

\r\n 3. Use the Correct Format in Financial Documents\r\n <\/h3>\r\n

\r\n When writing a cheque for $21, the amount in words can be written as follows, depending on the bank's required format:\r\n <\/p>\r\n

\r\n

\r\n Twenty-one and 00\/100 dollars\r\n <\/p>\r\n <\/div>\r\n

\r\n Note:<\/em> Follow the format accepted by your bank and write the amount clearly to help reduce the risk of alteration.\r\n <\/p>\r\n <\/div>\r\n\r\n<\/div>\r\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
