During the class, teacher introduced john with a new word "proper fraction”. Can you identify which of the following is a proper fraction?
4/9
Proper fraction is the fraction whose numerator is less than denominator i.e. numerator represents the number of parts into which whole is divided and denominator represents the number of parts which have been considered. Here, 4/9 is the only fraction whose denominator is greater than numerator. Hence, we can call 4/9 as a proper fraction.
