I know how to do this one, however, I need to know if I rounded correctly
Between July 1, 2000, and July 1, 2007, the estimated population of a city declined from 5360 to 4669. What was the percent decrease to the nearest tenth? (Round to one decimal place as needed.)

hmm..
I think you're very close but you may have made a few slight errors :)
So you want to do
5360 - 4669 = 691
Then we want to see how much that is OF the original amount.
So, 691/ 5360 = 0.1289.... 
But to find it as a percentage, we would need to multiply it by 100.
So 0.1289...  * 100 = 12.89 %

Now if you look at the question, it asks for the nearest tenth (so 1 decimal point)

anonymous · Answer
