  数词加减乘除的表示法
  1. “加”用plus,and或add表示;“等于”用is,make,equal等词表示。

  2. “减”用 minus或 take from表示

  十减去六等于四
  3. “乘”用time(动词)或multiply表示

  五、分数表示法
  1. 分数是由基数词和序数词一起来表示的。基数词作分子,序数词作分母,除了分子是“1”以外,其它情况下序数词都要用复数形式。
  3/4 three fourths或 three quarters
  1/3 one third或a third
  24/25 twenty-four twenty-fifths
  3 1/4 three and one fourth或 three and one quarter
  1/2 a half

  2. 当分数后面接名词时,如果分数表示的值大于1,名词用复数;小于1,名词用单数。
  1 1/2 hours 一个半小时(读作 one and a half hours)
  2 3/4 meters 二又四分之三米(读作two and three-fourths meters)
  4/5 meter 五分之四米

  3. 表示“n次方”的说法:指数用序数词,底数用基数词。
  10的7次方 the seventh power of ten(ten to the seventh power)
  6的10次方 the tenth power of six(six to the tenth power)
