§ 11-309

(a) If any commodity or service is sold, offered, exposed, or advertised for sale by weight, measure, or count, the price may not be misrepresented or represented in any manner calculated or tending to mislead or deceive an actual or prospective purchaser.

(b) If an advertised, posted, or labeled price per unit of weight, measure, or count includes a fraction of a cent, every element of the fraction shall be displayed prominently and the numerals expressing the fraction shall be immediately adjacent to, of the same general design and style as, and at least one half the height and width of any numeral representing the whole cents.
