I think that "No less than" is used with uncountable nouns and "No fewer than" with plural nouns? However, I have read the examples below in Oxford and Macmillan Dictionaries, so I am very confused about the uses of 'no less than' and 'no fewer than'. 1/ The hamburgers should contain no less than 50% meat. (Macmillan Dictionary) 2/ The guide contains details of no less than 115 hiking routes. ( Oxford Dictionary) 3/ There are no fewer than 100 different species in the area.( Oxford Dictionary) Would you please tell me the uses of no less than andno fewer than? Thanks in advance.
