英语中分数式怎么读?举个简单的例子,二分之一等于一乘以一除以二要怎么用英语表达?

基数词,序数词即可
二分之一：one half
三分之一：one third
三分之二：one thirds
one multiplied by one then divided by two is one half.这句还可再斟酌.能否one half is equal to one multiplied byone then divided by two ?嗯，这样的说法更贴切一些。我说的is在这儿显得有点别扭。这个好。One second is equal to one multiple one and minus two？这样呢？用被动和不用被动都可以吗“乘”用time（动词）或multiply表示　　3X4＝? How much is three times four?　　3X4=12　　Three times four is/are twelve．　　Multiply three by four，we get twelve．　　Three multiplied by four makes twelve．　　三乘以四等于十二“除”用divide的过去分词形式表示　　16÷4=? How much is sixteen divided by four?　　16÷4＝4　　Sixteen divided by four is four．　　Sixteen divided by four equals/gives/makes four．　　十六除以四等于四。
