12.4 is what percent of 174.4 - 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 174.4 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 174.4, so we can write it down as 100%=174.4.
4. We know, that x% equals 12.4 of the output value, so we can write it down as x%=12.4.
5. Now we have two simple equations:
1) 100%=174.4
2) x%=12.4
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%=174.4/12.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12.4 is what percent of 174.4

100%/x%=174.4/12.4
(100/x)*x=(174.4/12.4)*x       - we multiply both sides of the equation by x
100=14.064516129032*x       - we divide both sides of the equation by (14.064516129032) to get x
100/14.064516129032=x
7.1100917431193=x
x=7.1100917431193

now we have:
12.4 is 7.1100917431193% of 174.4
