5.09 is what percent of 550 - 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 550 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 550, so we can write it down as 100%=550.
4. We know, that x% equals 5.09 of the output value, so we can write it down as x%=5.09.
5. Now we have two simple equations:
1) 100%=550
2) x%=5.09
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%=550/5.09
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5.09 is what percent of 550

100%/x%=550/5.09
(100/x)*x=(550/5.09)*x       - we multiply both sides of the equation by x
100=108.05500982318*x       - we divide both sides of the equation by (108.05500982318) to get x
100/108.05500982318=x
0.92545454545455=x
x=0.92545454545455

now we have:
5.09 is 0.92545454545455% of 550
