answering probability questions with fractions on GCSE

are you allowed to do this or does it have to be a number between 0-1

No, it can be whatever you want. A probability of 0.1, for example, can be expressed as 10% or 1/10 as well. All 3 mean the same thing, it's just whatever you prefer/find easiest to understand.

Just bear in mind that it is possible for the question to require an answer in a particular format e.g. fraction or decimal e.t.c.

A fraction such as 1/6 IS a number between 0-1
Sometimes it is best to use fractions to easily calculate an exact result especially on non-calculator papers. If the probability that you roll a 6 on a fair dice is 1/6 and the probability that you deal a king from a pack of playing cards is 1/13 then the probability of rolling a six and dealing a king is 1/6 x 1/13.
