123.26 is what percent of 657.4 - 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 657.4 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 657.4, so we can write it down as 100%=657.4.
4. We know, that x% equals 123.26 of the output value, so we can write it down as x%=123.26.
5. Now we have two simple equations:
1) 100%=657.4
2) x%=123.26
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%=657.4/123.26
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 123.26 is what percent of 657.4

100%/x%=657.4/123.26
(100/x)*x=(657.4/123.26)*x       - we multiply both sides of the equation by x
100=5.3334415057602*x       - we divide both sides of the equation by (5.3334415057602) to get x
100/5.3334415057602=x
18.749619714025=x
x=18.749619714025

now we have:
123.26 is 18.749619714025% of 657.4
