How it's used

Used primarily as a suffix to describe numerical proportions or ratios between two quantities. It is almost always preceded by two numbers or values to indicate the specific split. While it functions as a noun, it is rarely used on its own without the preceding numbers defining the ratio.

Common mistake

Learners often confuse this with the verb 比 meaning to give. Remember that when used as a noun for ratio, it typically follows numbers, whereas the verb appears before an object.
