    Exclamation A questions about % change in values .?

    Hello Everyone,
    I am trying to understand a concept on which I am confused right now I'll appreciate an explanation on my questions. My question is as follows:

    When we calculate % increase from 1331046 to 3715393 it comes out at 179%. Now why I dont get 3715393 when I multiply 1331046 by 179%?

    Also when we divide 3715393 by 1331046 it gives 2.791, which when multiplied by 1331046 gives us 3715393. So how this calculation is described in plaint english.

    I'll appreciate any help. Thanks in advance.

    The reason you aren't getting the right answer is because you are calculating the percent, while the problem asks for the percent increase.

    When looking for the percent increase, you must first subtract the two numbers to find how much it increased by. Then you find the percent. The formula looks like this:
    (New Number - Original Number) / (Original Number)

    For your specific example it would look like this:
    (3715393 - 1331046) / 1331046

    I hope this helps
