找出句中的错误并改正

Two fifth of the students will go on a field trip next Sunday.

Answer 1

答案：
解析：

Two fifths of the students will go on a field trip next Sunday. 　　分析与解答：本句考查分数的表达方法。在英语中，分数中的分子要用基数词计数，分母用序数词计数，同时当分子是1以上的数字时，分母要用复数形式；分子为1时，分母采用单数形式。如“1/2: one second；1/3: a third；4/7: four sevenths等。特殊的表达法还有: a half(1/2), a quarter(1/4), three quarters(3/4)等。所以本题应改为：Two fifths of the students will go on a field trip next Sunday.
