1.23 is what percent of 25.9 - 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 25.9 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 25.9, so we can write it down as 100%=25.9.
4. We know, that x% equals 1.23 of the output value, so we can write it down as x%=1.23.
5. Now we have two simple equations:
1) 100%=25.9
2) x%=1.23
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%=25.9/1.23
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.23 is what percent of 25.9

100%/x%=25.9/1.23
(100/x)*x=(25.9/1.23)*x       - we multiply both sides of the equation by x
100=21.056910569106*x       - we divide both sides of the equation by (21.056910569106) to get x
100/21.056910569106=x
4.7490347490347=x
x=4.7490347490347

now we have:
1.23 is 4.7490347490347% of 25.9
