12.58 is what percent of 63.58 - 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 63.58 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 63.58, so we can write it down as 100%=63.58.
4. We know, that x% equals 12.58 of the output value, so we can write it down as x%=12.58.
5. Now we have two simple equations:
1) 100%=63.58
2) x%=12.58
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%=63.58/12.58
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.58 is what percent of 63.58

100%/x%=63.58/12.58
(100/x)*x=(63.58/12.58)*x       - we multiply both sides of the equation by x
100=5.0540540540541*x       - we divide both sides of the equation by (5.0540540540541) to get x
100/5.0540540540541=x
19.786096256684=x
x=19.786096256684

now we have:
12.58 is 19.786096256684% of 63.58
