What is 18.5 in a fraction

37/2

Step-by-step explanation:

If you think of this like 18 1/2, there is a trick you can use:

Multiply the denominator by the whole number (in this case it would be 18 times 2, which equals 36).

Then add the numerator (in this case it would 36 + 1, which equals 38).

Since the original fraction was over two, keep the denominator, so your final answer is 37/2.
