211.82 is what percent of 1715.2 - 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 1715.2 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 1715.2, so we can write it down as 100%=1715.2.
4. We know, that x% equals 211.82 of the output value, so we can write it down as x%=211.82.
5. Now we have two simple equations:
1) 100%=1715.2
2) x%=211.82
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%=1715.2/211.82
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 211.82 is what percent of 1715.2

100%/x%=1715.2/211.82
(100/x)*x=(1715.2/211.82)*x       - we multiply both sides of the equation by x
100=8.0974412236805*x       - we divide both sides of the equation by (8.0974412236805) to get x
100/8.0974412236805=x
12.349580223881=x
x=12.349580223881

now we have:
