55.5 is what percent of 818 - 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 818 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 818, so we can write it down as 100%=818.
4. We know, that x% equals 55.5 of the output value, so we can write it down as x%=55.5.
5. Now we have two simple equations:
1) 100%=818
2) x%=55.5
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%=818/55.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 55.5 is what percent of 818

100%/x%=818/55.5
(100/x)*x=(818/55.5)*x       - we multiply both sides of the equation by x
100=14.738738738739*x       - we divide both sides of the equation by (14.738738738739) to get x
100/14.738738738739=x
6.7848410757946=x
x=6.7848410757946

now we have:
55.5 is 6.7848410757946% of 818
