英语里数字的读法一般是由,号隔开,有单纯的hundert（百）,thousand（千）,million（百万）,billion(十亿)组成的.一般是3位数字3位数字,号隔开读.743,850 seven hundert and fourty-three /thousand /eight hundert and fifty (就是前面的数字照常读,第一个逗号就是thousand,我用斜干分开,你好看清楚)19.505 ninty /point/ five hundert and five (小数点读point)50,908.05 fifty /thousand/ nine hundert and eight /point/ five (同样小数点是Point,前面的读法照样是“三三制”)诚心为你解答,给个好评吧亲,
