322.4 is what percent of 4030 - 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 4030 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 4030, so we can write it down as 100%=4030.
4. We know, that x% equals 322.4 of the output value, so we can write it down as x%=322.4.
5. Now we have two simple equations:
1) 100%=4030
2) x%=322.4
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%=4030/322.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 322.4 is what percent of 4030

100%/x%=4030/322.4
(100/x)*x=(4030/322.4)*x       - we multiply both sides of the equation by x
100=12.5*x       - we divide both sides of the equation by (12.5) to get x
100/12.5=x
8=x
x=8

now we have:
322.4 is 8% of 4030
