老师关于express sth as a percentage怎么样进行翻译呢？
又如例句：
These figures are expressed as a percentage of the total. 怎么样进行翻译？ a percentage of the total 怎么样理解？
Spending on research and development as a percentage of profits. 怎么样翻译？ a percentage of profits怎么样理解？
首次提问，不了解网站的规则，辛苦老师解答。
These figures are expressed as a percentage of the total.
本句的结构是：express these figures as... “以......方法表示这类数字”。 a percentage of the total “占总数的百分比”。
被动语态的意思是：这类数字以占总数的百分比来表示。
Spending on research and development as a percentage of profits.
这是个词组，不是句子。
spending on...“在......方面的支出”。
research and development “研究开发”（研发）。
as a percentage of profits “占收益的百分比”。
词组的意思是：研发支出占收益的百分比。
