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
