449.5 is what percent of 525 - 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 525 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 525, so we can write it down as 100%=525.
4. We know, that x% equals 449.5 of the output value, so we can write it down as x%=449.5.
5. Now we have two simple equations:
1) 100%=525
2) x%=449.5
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%=525/449.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 449.5 is what percent of 525

100%/x%=525/449.5
(100/x)*x=(525/449.5)*x       - we multiply both sides of the equation by x
100=1.1679644048943*x       - we divide both sides of the equation by (1.1679644048943) to get x
100/1.1679644048943=x
85.619047619048=x
x=85.619047619048

now we have:
449.5 is 85.619047619048% of 525
