129.38 is what percent of 1049 - 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 1049 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 1049, so we can write it down as 100%=1049.
4. We know, that x% equals 129.38 of the output value, so we can write it down as x%=129.38.
5. Now we have two simple equations:
1) 100%=1049
2) x%=129.38
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%=1049/129.38
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 129.38 is what percent of 1049

100%/x%=1049/129.38
(100/x)*x=(1049/129.38)*x       - we multiply both sides of the equation by x
100=8.1078992116247*x       - we divide both sides of the equation by (8.1078992116247) to get x
100/8.1078992116247=x
12.333651096282=x
x=12.333651096282

now we have:
129.38 is 12.333651096282% of 1049
