Express the number 1045 in words.

• A. One thousand and forty-five
• B. One thousand forty five
• C. One thousand four hundred forty-five
• D. One thousand forty-five

Answer: (D)

In writing numbers aloud, you break the number into thousands and the remainder. 1045 is 1,000 plus 45. Say the thousands part as “one thousand,” and the remainder 45 as “forty-five.” Put them together with a space and a hyphen in the two-word number, giving “one thousand forty-five.” The use of “and” after the thousand is a stylistic choice in some dialects, but the form shown here follows the common American-style convention without that connector. The other options either add an extra hundred that isn’t there, drop the hyphen, or imply a different value. So the correct expression is one thousand forty-five.
