330.6 is what percent of 478 - 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 478 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 478, so we can write it down as 100%=478.
4. We know, that x% equals 330.6 of the output value, so we can write it down as x%=330.6.
5. Now we have two simple equations:
1) 100%=478
2) x%=330.6
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%=478/330.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 330.6 is what percent of 478

100%/x%=478/330.6
(100/x)*x=(478/330.6)*x       - we multiply both sides of the equation by x
100=1.4458560193587*x       - we divide both sides of the equation by (1.4458560193587) to get x
100/1.4458560193587=x
69.163179916318=x
x=69.163179916318

now we have:
330.6 is 69.163179916318% of 478
