120.81 is what percent of 1305 - 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 1305 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 1305, so we can write it down as 100%=1305.
4. We know, that x% equals 120.81 of the output value, so we can write it down as x%=120.81.
5. Now we have two simple equations:
1) 100%=1305
2) x%=120.81
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%=1305/120.81
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 120.81 is what percent of 1305

100%/x%=1305/120.81
(100/x)*x=(1305/120.81)*x       - we multiply both sides of the equation by x
100=10.80208592004*x       - we divide both sides of the equation by (10.80208592004) to get x
100/10.80208592004=x
9.2574712643678=x
x=9.2574712643678

now we have:
120.81 is 9.2574712643678% of 1305
