    I understand your question. But you first have to understand what a percentage is to answer the question

    if one dollar is 100 pennies, then 100% of one dollar is 100 pennies. Do you follow that?

    So the key to understanding this problem, or any problem with percentages is to know that percent refers to 100

    So if you take 20% from 100% how much is left?

    now you have 6 and you want to take 20% away. So, you can multiply by 80%
