What type of fraction is 11/20?

The fraction 11/20 is classified as a proper fraction because the numerator (11) is less than the denominator (20). In proper fractions, the value of the top number is always less than that of the bottom number, which reflects parts of a whole. For example, with 11/20, it indicates that you have 11 parts out of a total of 20 equal parts, which is less than a whole (1).

In contrast, an improper fraction would have a numerator greater than or equal to the denominator, indicating more than a whole unit. A mixed number, on the other hand, combines a whole number with a fraction, which isn't applicable here since 11/20 is solely a fraction without any whole number component. The option "None of the above" would not be suitable as the fraction clearly fits into the category of a proper fraction.
