354.16 is what percent of 390.2 - 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 390.2 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 390.2, so we can write it down as 100%=390.2.
4. We know, that x% equals 354.16 of the output value, so we can write it down as x%=354.16.
5. Now we have two simple equations:
1) 100%=390.2
2) x%=354.16
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%=390.2/354.16
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 354.16 is what percent of 390.2

100%/x%=390.2/354.16
(100/x)*x=(390.2/354.16)*x       - we multiply both sides of the equation by x
100=1.1017619155184*x       - we divide both sides of the equation by (1.1017619155184) to get x
100/1.1017619155184=x
90.763710917478=x
x=90.763710917478

now we have:
354.16 is 90.763710917478% of 390.2
