18.12 is what percent of 1250 - 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 1250 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 1250, so we can write it down as 100%=1250.
4. We know, that x% equals 18.12 of the output value, so we can write it down as x%=18.12.
5. Now we have two simple equations:
1) 100%=1250
2) x%=18.12
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%=1250/18.12
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.12 is what percent of 1250

100%/x%=1250/18.12
(100/x)*x=(1250/18.12)*x       - we multiply both sides of the equation by x
100=68.984547461369*x       - we divide both sides of the equation by (68.984547461369) to get x
100/68.984547461369=x
1.4496=x
x=1.4496

now we have:
18.12 is 1.4496% of 1250
