    lessanchez, do you think you could clarify on that a little bit? What do you want to figure out?

    You put 15 over 50 and convert that into percentage.

    Also if you noticed it, 10% of 50 is 5, so 30% of 50 is just 3*5, 15

    Percentages have a lot of shortcuts, and noticing them will help you get the answers really quickly.

    I want you to try this one with just a nudge from me. If 10% of 25 is 2.5, how do we get to 80%?

    Think about it, if 10% is 2.5, to get to 80% we multiply by 8. So now what do you think it is?

    Not "percent", but the answer is 20. You could have also done it backwards, and figured out the difference between 80% and 100%, since we know that 100% is equal to 25. The difference in percent is 20%, and 10% we know is equal to 2.5, so 2 times that is 5. 25-5=20, which is the same as what you got, but with smaller numbers.

    A baseball bat is on sale for $40.00. It has been discounted at 75%. What was the original price of the bat?

    We now have the opposite information, so we want to work backwards. 75% is equal to 40, and we need 25% more to reach the full number. That 25% is also equal to 1/3 of 40, because 25/75=1/3. So to find the full number, we need to find 1/3 of 40, and add that to 40. Does that make sense?

    so the answer is 60

    It can't be 60, because 40 is not 75% of 60 (it is actually 67%). Find 1/3 of 40, and add it to 40.
