Problem with Percentages

I need some help with Percentages, I don't know that much about math. I pretty much every other area in math figured out but this one, and the explanations I get for it don't help. I always get the beginning and then get given the end result but no way to figure it out for myself.

Any help at all would be very much appreciated!!

Re: Problem with Percentages

Hi ReflectionsInInk;

Welcome to the forum! Can you be a little more specific? So I can help. Do you have a problem like 23% of something?

Say you needed 43% of 125 dollars. You convert the 43% into a decimal by dividing by 100.

43% / 100 = .43 Now you multiply.

.43 * 125 = 53.75 and converted back to money 53 dollars and 75 cents.

Say a pair of pants is marked down 12%. The original price is $31.00. What do you expect to pay for the pants?

Hi Bobby,

I kept trying until I got the answer, I guess I needed to look at it with a clear head, or learn MORE

The problem> 425 % 35= 420 r 5 or 420 reminder 5.

Thank you!:D

Re: Problem with Percentages

Hi Ms. Ink;

Glad to help if I did. I have one small problem, what do you mean by

425 % 35= 420 r 5 or 420 reminder 5.

I am not following that at all. Is it a question or an answer? What is it an answer to?

If two or more thoughts intersect, there has to be a point!

Oh sorry Bobbym, upon reading my last post I see what you mean, I did not post everything. In to big of a hurry.

The problem was this>>  425 % 35 =

With four options to choose from.

    a. 12 remainder 10
    b. 12
    c. 5 remainder 12
    d. 12 remainder 5

Answer should be A. 12 Reminder 10

Re: Problem with Percentages

Hi;

You are confusing percentages with quotients and remainders. In some programming languages like C++ and Java, % stands for modulo or remainder.

425 % 35 = 5 because 425 when divided bt 35 leaves a remainder of 5.

That's what I was thinking, looking at it again, now it might show up as percentage but it doesn't read or figure like percentage.

Yeah, though it would be nice if they wouldn't put the percentage on there so it that "LOOKS" like a percentage.

Re: Problem with Percentages

Hi;

Yes, you are using the percentage sign as I have said in the programming sense. It has a different meaning in everyday life. There it means percentage.
