Nine and three-fourths is not incorrect but it's not common useage. Nine and three-quarters is the way most native English-speakers would say it.
Fractions are spoken as ordinal numbers (third(s), fifth(s), sixth(s) etc) with two exceptions: 1/2 one (or a) half, likewise 1/4 and 3/4 are quarters (at least in UK English, I think "fourths" is used sometimes in US English) You wouldn't normally use 2/4 and 4/4 because they can be reduced to 1/2 and 1 respectively.
