1/2可以读为onehalf或oneovertwo。1/3是onethird，1/4是onefourth，但是注意1/2不能读成onesecond（一秒）。一个半小时，一般说成oneandahalfhours。注意几点：在日常生活中，用onequarter表示1/4比用onefourth更多一些；2/3要说twothirds,也就是说分母那个third要加s，不要忘记。另外，在数学中，也常将1/2说成oneovertwo，2/3说成twooverthree，且在表达比较复杂的分数的时候，比如17/820时，一般说成seventeenovereighthundredandtwenty。ExpressionofNumber1又1/23又2/322/3795/711/133又5/7

两个半小时三分半钟两小时十五分钟PracticeExpressionofNumber时间的读法是先读时,再读分。像4:28读为fourtwenty-eight。至于整点的情况，读法就更简单了，4:00读为It’sfouro’clock，It’sfour或者It’sfoursharp。再比如4:05，一般不读成fourfive，而要读成fourofive或者更书面一些的fivepastfour，但是这类表示方法现在用的相对较少，人们更倾向用表达更方便的前者。
