如何表达分数
1.分数的说法是分子在前、分母在后。分子以基数(one,two,three)表示,分母以序数(first,second,third)等表示。
比如:1/7 = one-seventh,a seventh 1/3 = one-third,a third
2.分子超过1时,分母必须加上-s。
比如:3/5 = three-fifths 2/6 = two-sixths
3.分数中的分母为2时,要用half表示,但不可以用second
比如:1/2 = one-half,a half
4.分母为4时,除了用fourth外也可以用quarter
比如:1/4 = one-fourth,one-quarter 3/4 = three-fourths,three-quarters
5.带有整数的分数,整数部分要用基数来说,并用and和分数连接。
比如:8 1/2 = eight and a half,eight and one-half
6. 如果碰到复杂的分数时,只要在分母和分子的中间加上over就可以了。
比如:327/465 = three hundred and twenty-seven over four hundred and sixty-five
