1. We assume, that the number 0.00017175 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 0.00017175, so we can write it down as 100%=0.00017175.
4. We know, that x% equals 7.78E-6 of the output value, so we can write it down as x%=7.78E-6.
5. Now we have two simple equations:
1) 100%=0.00017175
2) x%=7.78E-6
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%=0.00017175/7.78E-6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.78E-6 is what percent of 0.00017175
