「English also tends to use the plural with decimal fractions, even if less than one, as in 0.3 metres, 0.9 children.」 (維基百科，關鍵字：plural、linguistics) 由此可知，在十進制分數(俗稱小數)中是要用複數(plural、眾數[非統計學中特殊名詞]) 的，即使小於1，也要使用複數。「Common fractions less than one tend to be used with singular expressions: half (of) a loaf, two-thirds of a mile.」 (維基百科，關鍵字：plural、linguistics) 另外，由這句話可知道，在common fractions中，是要用單數的。「A common fraction (also known as a vulgar fraction or simple fraction) is a rational number written as a/b or , where the integers a and b are called the numerator and the denominator, respectively.[2] The numerator represents a number of equal parts and the denominator, which cannot be zero, indicates how many of those parts make up a unit or a whole. In the examples 2/5 and 7/3, the slanting line is called a solidus or forward slash. In the examples and , the horizontal line is called a vinculum or, informally, a "fraction bar."」 (維基百科，關鍵字：fraction、mathematics) 上述為common fraction的定義。「Negative numbers are usually treated the same as the corresponding positive ones: minus one degree, minus two degrees. Again, rules on such matters differ between languages.」再者，上述為「負數」時，「複數」的使用方法。由此句話可知道，只要對應到其「正數」的部分，並且由「正數」的部分做為「單數」或「複數」決定之參考。 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 124.8.232.135
