• It would be 1/3 x 20 = 6.67 dollars, unless there was a special offer on like 3 pieces for the price of 2.

• How many times does 3 go into 20? 20/3.

You can write it out verbatim. 1 dollar per 3 bread. The per is usually written as a division, so (1 dollar / 3 bread). How much for 20 bread? (1 dollar / 3 bread = ? dollar / 20 bread. Multiple both sides by (20 bread) . The bread unit cancels to give you (20 / 3) dollar.
