447.5 is what percent of 4000 - 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 4000 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 4000, so we can write it down as 100%=4000.
4. We know, that x% equals 447.5 of the output value, so we can write it down as x%=447.5.
5. Now we have two simple equations:
1) 100%=4000
2) x%=447.5
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%=4000/447.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 447.5 is what percent of 4000

100%/x%=4000/447.5
(100/x)*x=(4000/447.5)*x       - we multiply both sides of the equation by x
100=8.9385474860335*x       - we divide both sides of the equation by (8.9385474860335) to get x
100/8.9385474860335=x
11.1875=x
x=11.1875

now we have:
447.5 is 11.1875% of 4000
