Foreigners often make some strange mistakes in Chinese when they study the most difficult language--- ---Chinese. We try to analyze typical sentences to correct these errors.
Zhèshì èr fēn zhī sān.
False: 这是二分之三。
Zhèshì sān fēn zhī èr.
True: 这是三分之二。
二分之三（two—thirds）是受英语分数表示方法的影响。英语要以分子为基数词，分母为序数词，并有复数。汉语的表示方法是先说分母，后说分子，应该为三分之二。
二分之三（two-thirds）is derived from the English way of showing fractions. In English, the numerator is a cardinal number wheras the denominatior is an ordinal number which may appear in the plural form. In Chinese, the denominatior always comes before the numerator. Thus it should be 三分之二.
