8.9E-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 8.9E-5 of the output value, so we can write it down as x%=8.9E-5.
5. Now we have two simple equations:
1) 100%=100
2) x%=8.9E-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%=100/8.9E-5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.9E-5 is what percent of 100

100%/x%=100/8.9E-5
(100/x)*x=(100/8.9E-5)*x       - we multiply both sides of the equation by x
100=1123595.505618*x       - we divide both sides of the equation by (1123595.505618) to get x
100/1123595.505618=x
8.9E-5=x
x=8.9E-5

now we have:
8.9E-5 is 8.9E-5% of 100
