分子大于1时，做分母的序数词用复数，因此五分之二的表达应该是 two fifths，排除B,D；分数后面的名词为复数名词students，根据主谓一致的原则，只能用are，故答案选 A。
点睛：本题考查的知识点有分数的表达和主谓一致，一般情况下，表示分数时，分子要用基数词，分母要用序数词，如果分子大于1，表示分母的序数词要用复数形式，如：two thirds 三分之二。
由“分数或百分数+名词”构成的短语作主语时，其谓语动词的数要根据短语中后面名词的数而定。
如：60% of the students in our class are girls. 我们班60%的学生是女生。
Two thirds of the apple is red.这个苹果的三分之二是红色的。
