one in ten是數字表達法嗎

one in ten這個英語短語的意思是“每十個中有一個”，這應該也可以算是數字表達法，相當於10 per cent。

如：One student in ten failed in the exam. 每十個學生中有一個考試沒及格。 One in ten suffered from the disease. 每十個人中有一個在遭受這種疾病。

是數字表達法，中文意思是十分之一，百分之十

A survey I conducted with Irene Whitney found that in British primary schools up to a quarter of pupils reported experience of bullying， which in about one in ten cases was persistent.
