5.18 is what percent of 83 - 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 83 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 83, so we can write it down as 100%=83.
4. We know, that x% equals 5.18 of the output value, so we can write it down as x%=5.18.
5. Now we have two simple equations:
1) 100%=83
2) x%=5.18
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%=83/5.18
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5.18 is what percent of 83

100%/x%=83/5.18
(100/x)*x=(83/5.18)*x       - we multiply both sides of the equation by x
100=16.023166023166*x       - we divide both sides of the equation by (16.023166023166) to get x
100/16.023166023166=x
6.2409638554217=x
x=6.2409638554217

now we have:
5.18 is 6.2409638554217% of 83
