如果带分数的整数部分是1/名词读在带分数之后时/名词要用复数；而名词读在1与分数之间时/名词则用单数。 例如： 1-1/2/tons读作：one and a half tons或one (a)ton and a half 1-1/3/miles读作：one and a third miles或one (a)mile and a third 与小数连用的名词的数：整数是零时/名词用单数形式/其他情况名词用复数形式。 例如： 0/27/metrezero point two seven of a metre1/26/metresone point two six metres 3/百分数：百分数用下面形式表示： 5%5/per cent(缩写：5/PC)读作：five percent 23%23/per cent(缩写：23/PC)读作：twenty-three percent 4/时刻表达法：表示时刻有两种说法： 1)先说分钟/后说钟点。几点过几分，分钟不超过三十分钟时用past。例如： Its five past seven now/ 现在是七点(过)五分。 几点差几分或差几分几点，差的分钟数不超过二十九分钟时/用to例如：Its twenty-nine to five/ 五点差二十九分。
