11.8 is what percent of 642.36 - 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 642.36 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 642.36, so we can write it down as 100%=642.36.
4. We know, that x% equals 11.8 of the output value, so we can write it down as x%=11.8.
5. Now we have two simple equations:
1) 100%=642.36
2) x%=11.8
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%=642.36/11.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 11.8 is what percent of 642.36

100%/x%=642.36/11.8
(100/x)*x=(642.36/11.8)*x       - we multiply both sides of the equation by x
100=54.437288135593*x       - we divide both sides of the equation by (54.437288135593) to get x
100/54.437288135593=x
1.8369761504452=x
x=1.8369761504452

now we have:
11.8 is 1.8369761504452% of 642.36
