400.3 is what percent of 6480 - 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 6480 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 6480, so we can write it down as 100%=6480.
4. We know, that x% equals 400.3 of the output value, so we can write it down as x%=400.3.
5. Now we have two simple equations:
1) 100%=6480
2) x%=400.3
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%=6480/400.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 400.3 is what percent of 6480

100%/x%=6480/400.3
(100/x)*x=(6480/400.3)*x       - we multiply both sides of the equation by x
100=16.187859105671*x       - we divide both sides of the equation by (16.187859105671) to get x
100/16.187859105671=x
6.1774691358025=x
x=6.1774691358025

now we have:
400.3 is 6.1774691358025% of 6480
