10 is what percent of 18721 - 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 18721 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 18721, so we can write it down as 100%=18721.
4. We know, that x% equals 10 of the output value, so we can write it down as x%=10.
5. Now we have two simple equations:
1) 100%=18721
2) x%=10
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%=18721/10
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 10 is what percent of 18721

100%/x%=18721/10
(100/x)*x=(18721/10)*x       - we multiply both sides of the equation by x
100=1872.1*x       - we divide both sides of the equation by (1872.1) to get x
100/1872.1=x
0.053415950002671=x
x=0.053415950002671

now we have:
10 is 0.053415950002671% of 18721
