Question

how to name this fraction 3/4
​

Answer 1

so the answer is 3 rase to 4

Answer 2

You call 3/4 "three fourths" or "three quarters", and 3/5 "three fifths". You say "three quarters of a cup" or "three fifths of a cup". In US English you sometimes come across "fourths" instead of "quarters" but that is unusual elsewhere.
