What is 2800000 percent of 0.25 - 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 0.25 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 0.25 is 100%, so we can write it down as 0.25=100%.
4. We know, that x is 2800000% of the output value, so we can write it down as x=2800000%.
5. Now we have two simple equations:
1) 0.25=100%
2) x=2800000%
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:
0.25/x=100%/2800000%
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 2800000% of 0.25

0.25/x=100/2800000
(0.25/x)*x=(100/2800000)*x       - we multiply both sides of the equation by x
0.25=3.5714285714286E-5*x       - we divide both sides of the equation by (3.5714285714286E-5) to get x
0.25/3.5714285714286E-5=x
7000=x
x=7000

now we have:
2800000% of 0.25=7000
