12.6 is what percent of 175.4 - 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 175.4 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 175.4, so we can write it down as 100%=175.4.
4. We know, that x% equals 12.6 of the output value, so we can write it down as x%=12.6.
5. Now we have two simple equations:
1) 100%=175.4
2) x%=12.6
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%=175.4/12.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.6 is what percent of 175.4

100%/x%=175.4/12.6
(100/x)*x=(175.4/12.6)*x       - we multiply both sides of the equation by x
100=13.920634920635*x       - we divide both sides of the equation by (13.920634920635) to get x
100/13.920634920635=x
7.1835803876853=x
x=7.1835803876853

now we have:
12.6 is 7.1835803876853% of 175.4
