Fractions

In the United States a point is used as decimal separator in writing: 1.5 = one point five or one and a half; 2.45 = two point forty-five or two point four five; 134.706 = one hundred thirty-four point seven ou six, etc.
Simple fractions are formed by two words: the nominator is cardinal number; the denominator is ordinal number.

Example:

6/7 = six sevenths; 2/5 = two fifths; 23/56 = twenty-three fifty-sixths; 1/2 = one half (this is an exception); 4 2/3 = four and two thirds. To designate percentage, the word 'percent' is used always in its singular form: 5% = five percent; 1% = one percent; 47% = forty-seven percent.
