Fractions are numbers between whole numbers. If a is a number less than 1 (for example, ½ or 0.7), then there are many fractions between a and 1. For example, if a = 0.6, then ¾ (or 0.75) is a fraction that is greater than a but less than 1.However, if a is equal to or greater than 1, then no fraction between a and 1 can exist, because 1 is already less than or equal to a.Example:If a = ⅔, then 5/6 is a fraction that is greater than ⅔ but less than 1.
