365.15 is what percent of 400 - 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 400 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 400, so we can write it down as 100%=400.
4. We know, that x% equals 365.15 of the output value, so we can write it down as x%=365.15.
5. Now we have two simple equations:
1) 100%=400
2) x%=365.15
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%=400/365.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 365.15 is what percent of 400

100%/x%=400/365.15
(100/x)*x=(400/365.15)*x       - we multiply both sides of the equation by x
100=1.0954402300424*x       - we divide both sides of the equation by (1.0954402300424) to get x
100/1.0954402300424=x
91.2875=x
x=91.2875

now we have:
365.15 is 91.2875% of 400
