half the denominator, so 4 is two and then divide the numerator by the denominator e.g. 14 divided by 2 = 7, the answer therefore is there are 7 halves in 14/4.
Or another way is to turn the improper fraction into a proper fraction:
4 goes into 14 three times with a remainder of 2 so the proper fraction is 3 2/4
3 is a whole number and therefore has 6 halves, 2/4 is a half, so add this to the 6 and you have 7 halves.
