65.11 is what percent of 438 - 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 438 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 438, so we can write it down as 100%=438.
4. We know, that x% equals 65.11 of the output value, so we can write it down as x%=65.11.
5. Now we have two simple equations:
1) 100%=438
2) x%=65.11
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%=438/65.11
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 65.11 is what percent of 438

100%/x%=438/65.11
(100/x)*x=(438/65.11)*x       - we multiply both sides of the equation by x
100=6.7270772538781*x       - we divide both sides of the equation by (6.7270772538781) to get x
100/6.7270772538781=x
14.865296803653=x
x=14.865296803653

now we have:
65.11 is 14.865296803653% of 438
