一个英语百分数表达上的问题,3-1/2,怎么翻译?
The economic recovery gained greater traction in the second half of last year. Real gross domestic product (GDP) is currently estimated to have risen at an average annual rate of more than 3-1/2 percent in the third and fourth quarters, up from a 1-3/4 percent pace in the first half.

Answer 1

经济复苏在去年下半年获得更大的牵引力.目前估计第三,四季度实际国内生产总值(GDP)增长超过3.5％的年平均增长率,高于上半年1.75％的步伐.
比照新闻中播报经济数据时的说法,个人觉得还是这样翻译比较好.
