25.3 is what percent of 122.4 - 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 122.4 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 122.4, so we can write it down as 100%=122.4.
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%=122.4
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%=122.4/25.3
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 122.4

100%/x%=122.4/25.3
(100/x)*x=(122.4/25.3)*x       - we multiply both sides of the equation by x
100=4.8379446640316*x       - we divide both sides of the equation by (4.8379446640316) to get x
100/4.8379446640316=x
20.669934640523=x
x=20.669934640523

now we have:
25.3 is 20.669934640523% of 122.4
