What is the percent of decrease from 320 to 32? A. 10% B. 90% C. 100% D. 288%

OpenStudy (anonymous):

oh yeah free medal for answer lol

OpenStudy (anonymous):

(How much it went down / original amount) x 100

OpenStudy (anonymous):

?

OpenStudy (anonymous):

Actually you don't even have to calculate it. Only 1 answer makes sense.

OpenStudy (anonymous):

so 100%

OpenStudy (anonymous):

100% decrease would take it to zero. not 32

OpenStudy (anonymous):

O.o i hate math

OpenStudy (anonymous):

This isn't even math. Just common sense. No calculating involved.

OpenStudy (anonymous):

From 320 to 32 is a pretty big decrease, but not quite 100%. Can you see that?

OpenStudy (anonymous):

Well, It's pretty obvious that a 10% decrease would drop it 32% Because 10% of 320 is 32. So how many times if you subtracted 32 from 320 would it take you to get to the final answer of 32. that amount of times multiplied by 10%

OpenStudy (anonymous):

thats alot of words O.o

OpenStudy (anonymous):

Whoops 32 not 32%

OpenStudy (anonymous):

-_-

OpenStudy (anonymous):

Ok, so let me make this simple for you

OpenStudy (anonymous):

i just dont understand... math is hard for me...

OpenStudy (anonymous):

10% of 320=32.

OpenStudy (anonymous):

So, How much percentage did you lose going to 10%?

OpenStudy (anonymous):

but 32 is not a answer :(

OpenStudy (anonymous):

22?

OpenStudy (anonymous):

I understand that. How much percentage did you lose going to 32?

OpenStudy (anonymous):

No.

OpenStudy (anonymous):

You start off at 100%

OpenStudy (anonymous):

78

OpenStudy (anonymous):

Then you go down to 10% what is the total loss?

OpenStudy (anonymous):

100-32=78

OpenStudy (anonymous):

78-10?

OpenStudy (anonymous):

No, 32 is the number you're trying to get too.

OpenStudy (anonymous):

which is 10% of the total number

OpenStudy (anonymous):

320.

OpenStudy (anonymous):

Ok, this is as simple as I can put it without giving you the answer.

OpenStudy (anonymous):

oooohhhhhh i seariously hate math

OpenStudy (anonymous):

288?

OpenStudy (anonymous):

If you're trying to get to 10% (which is 32)

OpenStudy (anonymous):

To find how much you lost do 100%-10%

OpenStudy (anonymous):

90%

OpenStudy (anonymous):

Yes! Perfect.

OpenStudy (anonymous):

Since you lost 90%, That would be the "Percent of Change"

OpenStudy (anonymous):

So that's your answer :)

OpenStudy (anonymous):

oh o.o that was easyr tan i thought thanks :D

OpenStudy (anonymous):

Yes, I hope this'll help you with future problems.

OpenStudy (anonymous):

yeah but i have3 more to ask :D

OpenStudy (anonymous):

Wow. :p

OpenStudy (anonymous):

The method I used to solve your problem is one I was never taught I self taught myself.

OpenStudy (anonymous):

sweet thats easy...but hard at the same time

OpenStudy (anonymous):

Find the percentage of the new number then subtract or add to 100% to find the change.

OpenStudy (anonymous):

o.o
