25.3 is what percent of 87.39 - 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 87.39 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 87.39, so we can write it down as 100%=87.39.
4. We know, that x% equals 25.3 of the output value, so we can write it down as x%=25.3.
5. Now we have two simple equations:
1) 100%=87.39
2) x%=25.3
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%=87.39/25.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 25.3 is what percent of 87.39

100%/x%=87.39/25.3
(100/x)*x=(87.39/25.3)*x       - we multiply both sides of the equation by x
100=3.4541501976285*x       - we divide both sides of the equation by (3.4541501976285) to get x
100/3.4541501976285=x
28.950680855933=x
x=28.950680855933

now we have:
25.3 is 28.950680855933% of 87.39
