Chinese expresses percentages as
百分之 + N, literally 'of one hundred parts, N' — the structure mirrors 'N out of 100' rather than English's 'N percent'. Note Chinese says the denominator first: '
百分之八十' = 'of-100-parts-80' = 80%. Full template:
百分之 + numeral, written either with characters (
百分之八十) or digits (
百分之80).
