Problem with Fraction format in Excel

Good day!
While it is true that we can use the Fraction format in the Number group (Home) to enter fractions as fractions and not date
(such as 1/5 and not 5-Jan, etc.).
How can we prevent Excel from automatically rounding off to 1/2 for fractions that are actually equal to 1/2 but we want it displayed the way we key-in the fraction (e.g. 3/6, 4/8, 5/10, etc).
Thanks a lot
