In the decade beginning with 1901,about 8.8 million immigrants entered the US. In the following decade, this number dropped to approximately 5.7 million people. Find the percent decrease, to the nearest whole percent.

What do you think the answer is? We can help you, but you must post an attempt.

If I thought I knew what the answer is I wouldn't be asking an ask website I've worked on it for 15 minutes and can't figure it out

Do you know the formula to determine percentage?

like, the percent * the total=the part, that ?

New value-old value/old value
then multiply the answer x100

How big was the decrease in millions? (forget the percentage right now)

OK I get it now. Yeah we haven't learned that, that would be why I wouldn't know thanks a bunch.

So, what did you get? Show me how you plugged your problem into the formula I gave you.

Sorry: try this
Original amount- new amount/divided by original amount
Then multiply x100
I typed it backwards before sorry!

My teacher gives us the answer since it is a review and I knew the answer would be 35% but didn't know how to get it so when you gave me that I did 5.7-8.8 and got -3.1 then divided that by 8.8 and got -.35 then mulitplied by 100 and got -35.23

The decrease was 3.3 million

3.1 million

8.8 - 5.7 = 3.1

8.8-5.7=3.1. 3.1 /8.8=35.227 which rounds to a decrease of 35%

Your question said to round to the nearest whole percentage

OK I got it now

Remember that you have to answer your original question. Do you understand how to do that?

My percent decrease would be 35%.

Yes! Just remember the formula

So if it were increase would I just add then divide by the original amount?

5.7 / 8.8 = 65%

35% + 65% = 100%

. No, it is:
New amount-original amount/ original amount, then multiply answer times 100%.

OK I understand that but there is another problem that says the number increases in 10 years so I added 252+398=650 and took 650/252=2.5793 I didn't think to multiply by 10 because the answer my teacher gave us is 57.9% but I kept getting the 2 in front of it then when I multiply by 10 I get 25.7936 so I don't know how my teacher got to the 57.9%

OK never mind what you said makes since now so I don't get the 2 I get the 5.7936
