I am having trouble multiplying and dividing numbers by percents.

The above is all true, however, your question is how to divide and multiply by percents. Please allow me to elaborate on the above answer. Consider that you are in a store shopping for a jacket. The sign says that the jacket is 25 percent off, and the price of the jacket costs $59.99. Follow the formula below:

59.99 (X) .25 (25%/100) = 14.9975 (or rounded up to 15), so the dollar amount off of the price of the jacket is $15.00.

Now to find the actual discounted price of the jacket you need to follow the steps below:

59.99 - 15.00 = 44.99

The same is done to find a percentage of increase.

In Florida, the sales tax on an item is 7%. Once you decide to purchase the jacket we mentioned earlier, you will need to know the amount of tax on that purchase:

$44.99 X .07 (7%) = 3.149 (or rounded up to 3.15)

44.99 + 3.15 = 48.14

So you will pay $48.14 for that $59.99 jacket.

I hope this helps you with working with percentages.

Remember your percentage will always be divided by 100, if you plug it on the calculator you will be able to get it as a decimal.

Ex: Let's say you have 2%

2/100
