438.54 is what percent of 470 - 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 470 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 470, so we can write it down as 100%=470.
4. We know, that x% equals 438.54 of the output value, so we can write it down as x%=438.54.
5. Now we have two simple equations:
1) 100%=470
2) x%=438.54
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%=470/438.54
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 438.54 is what percent of 470

100%/x%=470/438.54
(100/x)*x=(470/438.54)*x       - we multiply both sides of the equation by x
100=1.0717380398595*x       - we divide both sides of the equation by (1.0717380398595) to get x
100/1.0717380398595=x
93.306382978723=x
x=93.306382978723

now we have:
438.54 is 93.306382978723% of 470
