Fractional Numbers

Consider some popular type castings that we’re already familiar with. One or another object may have one or more of the following methods:

• .to_i: This converts something to an integer. For example, it converts a string to a number.

• .to_s: This converts something to a string. For example, it converts a number to a string.

• .to_f: This converts something to a fraction. For example, it converts a string to a fraction.
