51 is what percent of 18851 - 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 18851 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 18851, so we can write it down as 100%=18851.
4. We know, that x% equals 51 of the output value, so we can write it down as x%=51.
5. Now we have two simple equations:
1) 100%=18851
2) x%=51
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%=18851/51
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 51 is what percent of 18851

100%/x%=18851/51
(100/x)*x=(18851/51)*x       - we multiply both sides of the equation by x
100=369.62745098039*x       - we divide both sides of the equation by (369.62745098039) to get x
100/369.62745098039=x
0.27054267678107=x
x=0.27054267678107

now we have:
51 is 0.27054267678107% of 18851
