I think you meant to write 27/2
Improper fractions always have the larger number up top.
Use long division to find that 27/2 = 13 remainder 1
The 13 is the whole part and the remainder 1 will go over 2 to get 1/2
So we have 13 and 1/2 or 13&1/2 as the final answer
27/2 = 13 & 1/2

An alternative method is to break up 27 into 26+1, and simplify like so,
27/2 = (26+1)/2 = 26/2 + 1/2 = 13+1/2 = 13 & 1/2
which gets us the same result as before
