The fraction is written as a ratio and its proportion’s properties are most useful for solving problems. Discussions and debates over the doctrine of proportion or doctrine of proportionality, as contained in Euclid's Elements Book V, has had an interesting and varied history. Euclid's circuitous presentation of the theory of proportionality in Book V was presented independently from arithmetic proofs (discussed elsewhere in his treatise) due to commensurability issues.
