What is 2013 percent of 2015 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 2015 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 2015 is 100%, so we can write it down as 2015=100%.
4. We know, that x is 2013% of the output value, so we can write it down as x=2013%.
5. Now we have two simple equations:
1) 2015=100%
2) x=2013%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
2015/x=100%/2013%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 2013% of 2015

2015/x=100/2013
(2015/x)*x=(100/2013)*x       - we multiply both sides of the equation by x
2015=0.049677098857427*x       - we divide both sides of the equation by (0.049677098857427) to get x
2015/0.049677098857427=x
40561.95=x
x=40561.95

now we have:
2013% of 2015=40561.95
