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.

[jazzyjo94]

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

[teacherjenn4]

Do you know the formula to determine percentage?

[jazzyjo94]

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

[teacherjenn4]

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

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

[Wondergirl]

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

[jazzyjo94]

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

[jazzyjo94]

The decrease was 3.3 million

[Wondergirl]

the decrease was 3.3 million

3.1 million

8.8 - 5.7 = 3.1

[teacherjenn4]

the decrease was 3.3 million

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

[teacherjenn4]

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

[jazzyjo94]

OK I got it now

[jazzyjo94]

3.1 million

8.8 - 5.7 = 3.1

Right that's what I met I typed it wrong
So then what?

[Wondergirl]

right thats what i met i typed it wrong
so then what?

You and teacherjenn figured it out.

[teacherjenn4]

right thats what i met i typed it wrong
so then what?

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

[jazzyjo94]

My percent decrease would be 35%.
