Final answer:
The fraction '1/3' could symbolize a part of a series of events or judgments, but without specific context, it's challenging to provide an accurate meaning for its use with the first four trumpets.
Step-by-step explanation:
The fraction "1/3" mentioned in various contexts can have differing interpretations depending on the source material. From the references provided, the fraction is used to signify a portion of a larger whole, whether it's a piece of a pie in a mathematics-focused example, or metaphorically speaking to parts of a process like the trumpets that overthrew Jericho's walls.
However, without a specific context linking "1/3" to the first four trumpets, such as a religious or historical text, it's challenging to provide an accurate meaning. It could symbolize a part of a series of events or judgments especially considering the allusion to the trumpets used in the battle of Jericho, which is a biblical story.
