谁总结一下英语分数和小数的读法啊```
不胜感激```

分数
表示分数时,分子要用基数词,分母用序数词。如果分子大于1,分母必须用复数形式:
1/3→a(one)third
2/3→two thirds
1/4→a(one)quarter(或fourth)
3/7→three sevenths
1/2→应读作a(one)half
*比较复杂的分数如:24/789,多读作 twenty four over seven hundred and eighty nine。
小数
表示小数时,小数点前面的基数词和前面讲的基数词的读法相同;小数点后的数字则必须一一读出:
0.0089→(zero /naught)point zero zero eight nine
1.36→one point three six
百分数
百分数由percent表示,百分号%读作 percent,应用时常与by连用。
0.68%→zero point six eight percent
6%→six percent
369%→three hundred and sixty nine percent
The output of steel went up by 20 percent.钢产量增长20%。
The price of cotton was reduced by 20 percent.棉花的价格下降了20%。
The loss of water has been reduced to less than 30 percent.水的损耗减少到30%以下。

分数:分子用基数,即one two three……
分母用序数,即third, fourth……
1/2:one/a half
1/3: one third
2/3: two thirds(注意third变复数)
如果分数前还有整数的,可以加个and,如:two and three fourths

小数:关键是小数点,读point
小数点后,一个一个数地念
如:45.345 forty five point three four five

分数( one eighth、three eighths);小数(0.65 nought point six five);集合数字(1/4:one quarter、6:half a dozen、20:one score)等。
