Please take a look at the fraction strips above. The goal of the above was to match about 20 landmark fractions to their equivalent percents. The goal was not rely on memory, but to strategically think about the placement of these fractions. For example, most students immediately know that 1/2 = 50%. They can use that knowledge to "discover" that 1/4 = 25%, and then to find that 1/8 = 12.5%. Even the more difficult fractions like 1/6 become easy to place when there are landmark percents already present. 16 2/3 % is easy to place if 10% and 20% are already listed.
