15.6 is what percent of 258.2 - 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 258.2 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 258.2, so we can write it down as 100%=258.2.
4. We know, that x% equals 15.6 of the output value, so we can write it down as x%=15.6.
5. Now we have two simple equations:
1) 100%=258.2
2) x%=15.6
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%=258.2/15.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.6 is what percent of 258.2

100%/x%=258.2/15.6
(100/x)*x=(258.2/15.6)*x       - we multiply both sides of the equation by x
100=16.551282051282*x       - we divide both sides of the equation by (16.551282051282) to get x
100/16.551282051282=x
6.0418280402789=x
x=6.0418280402789

now we have:
15.6 is 6.0418280402789% of 258.2
