1089.08 is what percent of 1207.86 - 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 1207.86 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 1207.86, so we can write it down as 100%=1207.86.
4. We know, that x% equals 1089.08 of the output value, so we can write it down as x%=1089.08.
5. Now we have two simple equations:
1) 100%=1207.86
2) x%=1089.08
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%=1207.86/1089.08
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1089.08 is what percent of 1207.86

100%/x%=1207.86/1089.08
(100/x)*x=(1207.86/1089.08)*x       - we multiply both sides of the equation by x
100=1.1090645315312*x       - we divide both sides of the equation by (1.1090645315312) to get x
100/1.1090645315312=x
90.166078850198=x
x=90.166078850198

now we have:
