When a decimal is written in word form, what indicates whether the number can be written as a mixed number or as a fraction less than 1

9514 1404 393

  "and"

Step-by-step explanation:

Properly written, the word "and" separates the integer portion from the fractional portion of the number. If there is no "and", then there is no integer portion, so the number is a fraction less than 1.

Examples:

one and three tenths = 1 3/10

thirty-one thousandths = 31/1000
