What is the ratio of vowels to constant and in the word mathematics? (also how do u know)

Mathematics...total of 11 letters
vowels : there are 4 vowels (a,e,a,i)
consonants : there are 7 consonants (m,t,h,m,t,c,s)

so the ratio of vowels to consonants is : 4/7 or 4:7 or 4 to 7

It is 198,87032,750 + 375 = 33145 so, we take the 6% and we make it a decimal (0.6) and multiply that, then that is your answer
