1. 整数和小数的读法
3.24可以读作three point twenty-four或three twenty-four。在美国买东西都要含税, 所以价钱多半都带有小数点, 通常小数点可以说point，也可以直接省略。另外比较正式的说法为three dollars and twenty-four cents, 但是在一般日常生活中几乎是听不到这种读法，而是直接读为three twenty-four。在美国开支票的机会很多, 要注意的是，支票上小数的写和读与平时有所不同。在支票上，金额不仅要用阿拉伯数字写出，而且还要用英语在金额栏的最左边写出。其中整数部分的第一个字母要大写, 小数部分则用xx/100 来表示, 并在最后加上only。例如12.87 写为Twelve dollar and 87/100 only。
1,245 可读为twelve forty-five，one thousand two hundred and forty-five 或twelve
hundred and forty-five。一般来说, 四位数的读法是两个数字一起读, 如12-45。但有时为了让对方听得
更清楚(特别是跟钱有关的时候)，会把thousand 和hundred 读出来, 像上面的第二种读法。另外, 像第三种读法，美国人也很喜欢把one thousand two hundred 直接说成twelve hundred，例如1,200 可以读为twelve hundred，当然也可以说one thousand and two hundred，这就是我们从教科书上学的读法了。
五位数的读法是前两个数一组, 后两个一组，中间的自己一组。例如35,891 经常读为thirty-five thousand eight hundred and ninety-one。而六位数如100,000 则读为one hundred thousand。由于在英语中没有十万这个字, 所以十万要用one hundred thousand, 一亿要用one hundred million。这两个要多练习, 不然很难熟练运用。
整数中比较特殊的就是电话号码了，读电话号码的原则是在清楚的基础上，越简单越好。人们在读电话号码时，习惯一个数字一个数字地说, 以求清楚, 但有时为了方便起见, 也会以十位数为单位, 两个两个一起说。例如770-2145 可以读为seven seven zero, two one four five，也可以读为seven seven o, twenty-one forty-five。总之，不管如何读，一定要清楚，不要引起歧义。
2. 分数和科学记数的读法
1/2 可以读为one half 或one over two。1/2 的说法跟1/3、1/4 都不一样, 它不读为one second，而要用one half。而one of two 常用在数学上, 强调1 除以2, 这种说法在日常生活中用得比较少。至于1/3 是
one third，1/4 是one fourth等，大家对这种说法都已经很熟悉了，在此不多说，但要注意两点：在日常生活中，用one quarter 表示1/4比用one fourth 更多一些；2/3 要说two thirds, 也就是说分母那个third 要加s，不要忘记。

科学记数如1.23×10-4 可读为one point two three times ten to the minus four(negative four)；one point two three times ten minus four 或one point two three ten minus four。第一个是最正确的说法, 但有时为了简便会有不同程度的省略。像第二、三个省略适用在别人知道你在说科学符号的场合，例如老师上课时，或同学讨论功课时，不然别人有可能会误会你的意思。
3. 时间的读法
时间的读法是先读时, 再读分。像4:28 读为four twenty-eight。至于整点的情况，读法就更简单了，4:00 读为It's four o'clock. 或It's four.。在生活中，4:05 不是读为four five, 而是five past four或four o five；3:50 不是说three fifty，而是ten to four，当然也可以说成three fifty, 但是ten to four 这样的说法就相当于中文的"还有10分就四点了"；5:30 常说成five and half 或half past five，相当于中文的五点半了。
4. 一个重要的应用
在报地址的时候, 常有这种数字和英文字母混合的情况, 但是由于B, D 和T 读起来很容易混淆, 所以习惯上会加上一小句话来说明, 如  B as a in boy, T as in a teacher, D as in a dog。这样别人就可以很清楚地了解你在说哪个字母，这样，123D 就可以这么读：one two three D as in a dog。
