225.05 is what percent of 800 - 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 800 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 800, so we can write it down as 100%=800.
4. We know, that x% equals 225.05 of the output value, so we can write it down as x%=225.05.
5. Now we have two simple equations:
1) 100%=800
2) x%=225.05
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%=800/225.05
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 225.05 is what percent of 800

100%/x%=800/225.05
(100/x)*x=(800/225.05)*x       - we multiply both sides of the equation by x
100=3.5547656076427*x       - we divide both sides of the equation by (3.5547656076427) to get x
100/3.5547656076427=x
28.13125=x
x=28.13125

now we have:
225.05 is 28.13125% of 800
