Translation guide
The English word 'percentage' refers to a proportion or share expressed as a number out of 100. In Japanese, the concept is commonly expressed with the word パーセント (percent), but there are also native Japanese terms like 割合 (ratio/proportion) and 率 (rate) that are used in specific contexts. This guide helps learners choose the right expression depending on whether they are talking about a specific percentage number, a general proportion, or a statistical rate.
