56.8 is what percent of 321 - 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 321 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 321, so we can write it down as 100%=321.
4. We know, that x% equals 56.8 of the output value, so we can write it down as x%=56.8.
5. Now we have two simple equations:
1) 100%=321
2) x%=56.8
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%=321/56.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 56.8 is what percent of 321

100%/x%=321/56.8
(100/x)*x=(321/56.8)*x       - we multiply both sides of the equation by x
100=5.6514084507042*x       - we divide both sides of the equation by (5.6514084507042) to get x
100/5.6514084507042=x
17.694704049844=x
x=17.694704049844

now we have:
56.8 is 17.694704049844% of 321
