18 is what percent of 1626 - 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 1626 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 1626, so we can write it down as 100%=1626.
4. We know, that x% equals 18 of the output value, so we can write it down as x%=18.
5. Now we have two simple equations:
1) 100%=1626
2) x%=18
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%=1626/18
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18 is what percent of 1626

100%/x%=1626/18
(100/x)*x=(1626/18)*x       - we multiply both sides of the equation by x
100=90.333333333333*x       - we divide both sides of the equation by (90.333333333333) to get x
100/90.333333333333=x
1.1070110701107=x
x=1.1070110701107

now we have:
18 is 1.1070110701107% of 1626
