Hello all, Is there a rule about using en dashes for number spans when the numbers are spelt out, or if is there's a combination of spelt out numbers and digits used? (E.g. two-four, eight-12.) Something tells me this example is wrong. My instinct would be to write: two to four, eight to 12, 14-18, etc. I've searched through all my books (and the net) and can't find the answer anywhere! Thanks.
