383.5 is what percent of 445 - 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 445 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 445, so we can write it down as 100%=445.
4. We know, that x% equals 383.5 of the output value, so we can write it down as x%=383.5.
5. Now we have two simple equations:
1) 100%=445
2) x%=383.5
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%=445/383.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 383.5 is what percent of 445

100%/x%=445/383.5
(100/x)*x=(445/383.5)*x       - we multiply both sides of the equation by x
100=1.1603650586701*x       - we divide both sides of the equation by (1.1603650586701) to get x
100/1.1603650586701=x
86.179775280899=x
x=86.179775280899

now we have:
383.5 is 86.179775280899% of 445
