3/5
This depends on the context. However, it is good practice to reduce a ratio or a fraction to its lowest possible term. The only time you wouldn't simplify a ratio or fraction is if it signified something in its original state.
The lowest-term fraction can be obtained by finding the denominator and numerator by GCF. The lowest fraction can not be further reduced.
