What is 12.9 percent of 10251 - 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 10251 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 10251 is 100%, so we can write it down as 10251=100%.
4. We know, that x is 12.9% of the output value, so we can write it down as x=12.9%.
5. Now we have two simple equations:
1) 10251=100%
2) x=12.9%
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:
10251/x=100%/12.9%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 12.9% of 10251

10251/x=100/12.9
(10251/x)*x=(100/12.9)*x       - we multiply both sides of the equation by x
10251=7.7519379844961*x       - we divide both sides of the equation by (7.7519379844961) to get x
10251/7.7519379844961=x
1322.379=x
x=1322.379

now we have:
12.9% of 10251=1322.379
