25 is what percent of 547 - 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 547 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 547, so we can write it down as 100%=547.
4. We know, that x% equals 25 of the output value, so we can write it down as x%=25.
5. Now we have two simple equations:
1) 100%=547
2) x%=25
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%=547/25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 25 is what percent of 547

100%/x%=547/25
(100/x)*x=(547/25)*x       - we multiply both sides of the equation by x
100=21.88*x       - we divide both sides of the equation by (21.88) to get x
100/21.88=x
4.5703839122486=x
x=4.5703839122486

now we have:
25 is 4.5703839122486% of 547
