0.2 is what percent of 3500000 - 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 3500000 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 3500000, so we can write it down as 100%=3500000.
4. We know, that x% equals 0.2 of the output value, so we can write it down as x%=0.2.
5. Now we have two simple equations:
1) 100%=3500000
2) x%=0.2
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%=3500000/0.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.2 is what percent of 3500000

100%/x%=3500000/0.2
(100/x)*x=(3500000/0.2)*x       - we multiply both sides of the equation by x
100=17500000*x       - we divide both sides of the equation by (17500000) to get x
100/17500000=x
5.7142857142857E-6=x
x=5.7142857142857E-6

now we have:
0.2 is 5.7142857142857E-6% of 3500000
