The fraction of the total number of vowels to the total number of alphabets is a proper fraction.

The given statement is True.

A proper fraction is a fraction which has its numerator value less than the denominator.

Total number of alphabets = 26

Total number of vowels = 5

Fraction = $\frac{\mathrm{Total} \mathrm{number} \mathrm{of} \mathrm{alphabets}}{\mathrm{Total} \mathrm{number} \mathrm{of} \mathrm{vowels}}$ = $\frac{5}{26}$

In $\frac{5}{26}$, the value of the numerator is less than the denominator (5<26), So it is a proper fraction.
