4.5E-5 is what percent of 100 - 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 100 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 100, so we can write it down as 100%=100.
4. We know, that x% equals 4.5E-5 of the output value, so we can write it down as x%=4.5E-5.
5. Now we have two simple equations:
1) 100%=100
2) x%=4.5E-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:
100%/x%=100/4.5E-5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.5E-5 is what percent of 100

100%/x%=100/4.5E-5
(100/x)*x=(100/4.5E-5)*x       - we multiply both sides of the equation by x
100=2222222.2222222*x       - we divide both sides of the equation by (2222222.2222222) to get x
100/2222222.2222222=x
4.5E-5=x
x=4.5E-5

now we have:
4.5E-5 is 4.5E-5% of 100
