462.5 is what percent of 18500 - 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 18500 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 18500, so we can write it down as 100%=18500.
4. We know, that x% equals 462.5 of the output value, so we can write it down as x%=462.5.
5. Now we have two simple equations:
1) 100%=18500
2) x%=462.5
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%=18500/462.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 462.5 is what percent of 18500

100%/x%=18500/462.5
(100/x)*x=(18500/462.5)*x       - we multiply both sides of the equation by x
100=40*x       - we divide both sides of the equation by (40) to get x
100/40=x
2.5=x
x=2.5

now we have:
462.5 is 2.5% of 18500
