What is 1.24 percent of 12900000 - 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 12900000 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 12900000 is 100%, so we can write it down as 12900000=100%.
4. We know, that x is 1.24% of the output value, so we can write it down as x=1.24%.
5. Now we have two simple equations:
1) 12900000=100%
2) x=1.24%
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:
12900000/x=100%/1.24%
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 1.24% of 12900000

12900000/x=100/1.24
(12900000/x)*x=(100/1.24)*x       - we multiply both sides of the equation by x
12900000=80.645161290323*x       - we divide both sides of the equation by (80.645161290323) to get x
12900000/80.645161290323=x
159960=x
x=159960

now we have:
1.24% of 12900000=159960
