What is 2.0E-5 percent of 2490000 - 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 2490000 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 2490000 is 100%, so we can write it down as 2490000=100%.
4. We know, that x is 2.0E-5% of the output value, so we can write it down as x=2.0E-5%.
5. Now we have two simple equations:
1) 2490000=100%
2) x=2.0E-5%
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:
2490000/x=100%/2.0E-5%
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 2.0E-5% of 2490000

2490000/x=100/2.0E-5
(2490000/x)*x=(100/2.0E-5)*x       - we multiply both sides of the equation by x
2490000=5000000*x       - we divide both sides of the equation by (5000000) to get x
2490000/5000000=x
0.498=x
x=0.498

now we have:
2.0E-5% of 2490000=0.498
