17.6 is what percent of 25.2 - 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 25.2 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 25.2, so we can write it down as 100%=25.2.
4. We know, that x% equals 17.6 of the output value, so we can write it down as x%=17.6.
5. Now we have two simple equations:
1) 100%=25.2
2) x%=17.6
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%=25.2/17.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.6 is what percent of 25.2

100%/x%=25.2/17.6
(100/x)*x=(25.2/17.6)*x       - we multiply both sides of the equation by x
100=1.4318181818182*x       - we divide both sides of the equation by (1.4318181818182) to get x
100/1.4318181818182=x
69.84126984127=x
x=69.84126984127

now we have:
17.6 is 69.84126984127% of 25.2
