904.5 is what percent of 1018 - 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 1018 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 1018, so we can write it down as 100%=1018.
4. We know, that x% equals 904.5 of the output value, so we can write it down as x%=904.5.
5. Now we have two simple equations:
1) 100%=1018
2) x%=904.5
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%=1018/904.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 904.5 is what percent of 1018

100%/x%=1018/904.5
(100/x)*x=(1018/904.5)*x       - we multiply both sides of the equation by x
100=1.1254836926479*x       - we divide both sides of the equation by (1.1254836926479) to get x
100/1.1254836926479=x
88.85068762279=x
x=88.85068762279

now we have:
904.5 is 88.85068762279% of 1018
