分數(shù)
表示分數(shù)時，分子要用基數(shù)詞，分母用序數(shù)詞。如果分子大于1，分母必須用復數(shù)形式：
1／3→a（one）third
2／3→two thirds
1／4→a（one）quarter（或fourth）
3／7→three sevenths
1／2→應讀作a（one）half
＊比較復雜的分數(shù)如：24／789，多讀作 twenty four over seven hundred and eighty nine。
小數(shù)
表示小數(shù)時，小數(shù)點前面的基數(shù)詞和前面講的基數(shù)詞的讀法相同；小數(shù)點后的數(shù)字則必須一一讀出：
0．0089→（zero ／naught）point zero zero eight nine
1．36→one point three six
百分數(shù)
百分數(shù)由percent表示，百分號％讀作 percent，應用時常與by連用。
0．68％→zero point six eight percent
6％→six percent
369％→three hundred and sixty nine percent
