225000 is what percent of 7 - 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 7 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 100% equals 7, so we can write it down as 100%=7.
4. We know, that x% equals 225000 of the output value, so we can write it down as x%=225000.
5. Now we have two simple equations:
1) 100%=7
2) x%=225000
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:
100%/x%=7/225000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 225000 is what percent of 7

100%/x%=7/225000
(100/x)*x=(7/225000)*x       - we multiply both sides of the equation by x
100=3.1111111111111E-5*x       - we divide both sides of the equation by (3.1111111111111E-5) to get x
100/3.1111111111111E-5=x
3214285.7142857=x
x=3214285.7142857

now we have:
225000 is 3214285.7142857% of 7
