7.3E-11 is what percent of 3.305E-5 - 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 3.305E-5 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 3.305E-5, so we can write it down as 100%=3.305E-5.
4. We know, that x% equals 7.3E-11 of the output value, so we can write it down as x%=7.3E-11.
5. Now we have two simple equations:
1) 100%=3.305E-5
2) x%=7.3E-11
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%=3.305E-5/7.3E-11
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.3E-11 is what percent of 3.305E-5

100%/x%=3.305E-5/7.3E-11
(100/x)*x=(3.305E-5/7.3E-11)*x       - we multiply both sides of the equation by x
100=452739.7260274*x       - we divide both sides of the equation by (452739.7260274) to get x
100/452739.7260274=x
0.00022087745839637=x
x=0.00022087745839637

now we have:
7.3E-11 is 0.00022087745839637% of 3.305E-5
