128.7 is what percent of 1005.94 - 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 1005.94 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 1005.94, so we can write it down as 100%=1005.94.
4. We know, that x% equals 128.7 of the output value, so we can write it down as x%=128.7.
5. Now we have two simple equations:
1) 100%=1005.94
2) x%=128.7
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%=1005.94/128.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 128.7 is what percent of 1005.94

100%/x%=1005.94/128.7
(100/x)*x=(1005.94/128.7)*x       - we multiply both sides of the equation by x
100=7.8161616161616*x       - we divide both sides of the equation by (7.8161616161616) to get x
100/7.8161616161616=x
12.794003618506=x
x=12.794003618506

now we have:
128.7 is 12.794003618506% of 1005.94
