ELI5: What does it mean when a juice bottle says 10% juice? What does the rest of the 90% consist of and where does it come from?

When a juice bottle says it contains x% juice, what is the rest (100-x)% of it made of?

the 10% juice means 10% of the contents of that bottle come specifically from squeezing a fruit or vegetable (although not necessarily the one you expect, unless explicitly stated), or adding water to concentrate, or some combination of the above. The rest is going to be made up of the other contents of the ingredients list.
