What is the actual yield
Like theoretical yield, actual yield is a way to apply limiting reagents. The actual yield is the actual amount of the compound you get after the reaction has occurred.
For example if you have 20 cupcakes and enough icing for 15 cupcakes how many full cupcakes could you bring to Jessie's party? At first you would see that you could only possibly make 15 cupcakes because thats all you have enough icing for. After you ice all 15 cupcakes, however, you drop 3 on the ground. The actual yield for the amount of cupcakes you can bring to the party is therefore 12 cupcakes because you wouldn't want to bring cupcakes from the floor.
Here is another example. If you have 30 cupcakes and 19 liners, how many cupcakes are sold at the bake sale (cupcakes for the bake sale must be in lining)? Since the cupcakes liners are your limting reagent, the theoretical yield would be 19 cupcakes. After the bake sale you see that there are still 2 cupcakes sitting on the tray. The amount of cupcakes actually sold at the bake sale would be 17 (the actual yield) since you only had 19 to begin with, and still had two left over afterwards.

What is the percentage yield?
The percentage yield is very similar to the actual yield. The difference is that instead of having a number for your result, you have the percent of substance that was actually used, rather than the amount that could have been used.
For example, when taking a test John had the chance of getting 100% by getting every answer correct (the theoretical yield), however the day of the test he happened to be very tired. Therefore when he took the test he forgot the answers to 2 of the 50 questions, but still got the other 48 questions correct. What is the percentage of the test did John get correct? Since John got 48/50, the percentage of the test that he got correct was 96%, giving him a near perfect score.
