128.63 is what percent of 602.47 - 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 602.47 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 602.47, so we can write it down as 100%=602.47.
4. We know, that x% equals 128.63 of the output value, so we can write it down as x%=128.63.
5. Now we have two simple equations:
1) 100%=602.47
2) x%=128.63
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%=602.47/128.63
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 128.63 is what percent of 602.47

100%/x%=602.47/128.63
(100/x)*x=(602.47/128.63)*x       - we multiply both sides of the equation by x
100=4.6837440721449*x       - we divide both sides of the equation by (4.6837440721449) to get x
100/4.6837440721449=x
21.350440685843=x
x=21.350440685843

now we have:
