In february, alec had 1,525 visitors to his website. in march, he had 1,349 visitors to his website. what is the percentage decrease of the number of visitors to alec's website from february to march? if necessary, round to the nearest tenth of a percent.

To solve this, we begin by finding how many less visitors there were.  We do this by subtracting 1,349 from 1,525.  1,525 - 1,349 = 176.

Now, we find what percent of 1,525 176 is.  We do this by dividing 176 by 1,525 and multiplying the result by 100 to get a percent.  176/1,525 *100 = 11.54%, so the percent decrease was 11.54%.
