New Year Percentage?

2016% can be written as $\frac{2016}{100}$

$\frac{2016}{100}$ $\times$ $\frac{2015}{2016}$

= $\frac{2015}{100}$ = 20.15 = 2015%

2016% is $\frac{2016}{100}$ then 2016% of $\frac{2015}{2016}$ is $\frac{2016}{100}$ x $\frac{2015}{2016}$ that is equal to $\frac{2015}{100}$ equal to 2015%.

This is really very easy, 2016 = 2016, so we can cross out those 2016's, easy peasy! After that, we have 2015 left all alone, but where did that % go? Let's put it on the 2015! The answer is 2015%! Yay!!! That was super easy peasy! ( and FAST!)
