21.47 is what percent of 53.94 - 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 53.94 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 53.94, so we can write it down as 100%=53.94.
4. We know, that x% equals 21.47 of the output value, so we can write it down as x%=21.47.
5. Now we have two simple equations:
1) 100%=53.94
2) x%=21.47
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%=53.94/21.47
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.47 is what percent of 53.94

100%/x%=53.94/21.47
(100/x)*x=(53.94/21.47)*x       - we multiply both sides of the equation by x
100=2.5123428039124*x       - we divide both sides of the equation by (2.5123428039124) to get x
100/2.5123428039124=x
39.803485354097=x
x=39.803485354097

now we have:
21.47 is 39.803485354097% of 53.94
