5.7 is what percent of 320.8 - 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 320.8 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 320.8, so we can write it down as 100%=320.8.
4. We know, that x% equals 5.7 of the output value, so we can write it down as x%=5.7.
5. Now we have two simple equations:
1) 100%=320.8
2) x%=5.7
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%=320.8/5.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5.7 is what percent of 320.8

100%/x%=320.8/5.7
(100/x)*x=(320.8/5.7)*x       - we multiply both sides of the equation by x
100=56.280701754386*x       - we divide both sides of the equation by (56.280701754386) to get x
100/56.280701754386=x
1.7768079800499=x
x=1.7768079800499

now we have:
5.7 is 1.7768079800499% of 320.8
