Three-quarters are required to form a complete unit. Three-thirds is written as 3/3, which literally means three divided by three and is simplified to one. A fraction represents a portion of a whole, whereas one represents the total.
Any number greater than itself equals one. Using this information, two-thirds is a whole, four-fourths is a whole, ten-tenths is a whole, and so on. From a practical standpoint, one cup requires three-and-a-third-thirds of a cup, three-and-a-third-thirds of a tablespoon, and three-and-a-third-thirds of an inch.
