1 is what percent of 2190000 - 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 2190000 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 2190000, so we can write it down as 100%=2190000.
4. We know, that x% equals 1 of the output value, so we can write it down as x%=1.
5. Now we have two simple equations:
1) 100%=2190000
2) x%=1
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%=2190000/1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1 is what percent of 2190000

100%/x%=2190000/1
(100/x)*x=(2190000/1)*x       - we multiply both sides of the equation by x
100=2190000*x       - we divide both sides of the equation by (2190000) to get x
100/2190000=x
4.5662100456621E-5=x
x=4.5662100456621E-5

now we have:
1 is 4.5662100456621E-5% of 2190000
