One of four babies are now born to mothers aged thirty years or more, compared with just one of six born in 1975.

(A) of four babies are now born to mothers aged thirty years or more, compared with just one of six born

(B) of four babies is now born to a mother whose age is thirty or older, compared to just one of six babies who were born

(C) baby in four are now born to mothers aged thirty or older, compared to just one in six

(D) baby in four is now born to a mother aged thirty or older, compared with just one in six（D）

(E) baby in four is now born to mothers aged thirty years or more, compared to just one in six [D]

关于compare to 和compare with 我是清楚的一个表示比较，一个表示比喻 但是关于one of four babies 与one baby in four 我表示不清楚。
看到CD里有人说 one of four babies 后面加复数，one baby in four 后面加单数。又看到有说法

one of four babies：only 4 babies， pick up one one baby in four=one of every four babies

可是按照这样的解释one baby in four 表示的是25%的baby，为什么是加单数呢？

compare 这类短语比较的是前面的core noun One of four (babies) understood就可以省略掉了

我就是不明白为什么one baby in four 用的谓语动词是复数， one of four babies用的是单数。前者指的四个之中的一个baby,后者指四分之一的babies,不是吗？

one of + NOUN 后面加V动单复数看前面的noun~~同单同复。
