129.53 is what percent of 1260 - 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 1260 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 1260, so we can write it down as 100%=1260.
4. We know, that x% equals 129.53 of the output value, so we can write it down as x%=129.53.
5. Now we have two simple equations:
1) 100%=1260
2) x%=129.53
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%=1260/129.53
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 129.53 is what percent of 1260

100%/x%=1260/129.53
(100/x)*x=(1260/129.53)*x       - we multiply both sides of the equation by x
100=9.7274762603258*x       - we divide both sides of the equation by (9.7274762603258) to get x
100/9.7274762603258=x
10.280158730159=x
x=10.280158730159

now we have:
129.53 is 10.280158730159% of 1260
