This is an adult book about nutrition. There is a chart that I'm brailling in outline format that shows how many times per day children, teens and adults should eat grains, veggies, fruits, etc. So 3/day, 4-5/day, 2+/day appears many times. They are listed and are not in complete sentences. The instruction manual for transcribing uses a letter sign for $2/gal and the NBA bulletin uses a letter sign with $3/qt. The very wise sage I rely on says the letter sign is not needed for this situation, but I'm searching for better guidelines on when a letter sign is needed after a slash which follows a number.
