What is 1800 percent of 12800 - 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 12800 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 12800 is 100%, so we can write it down as 12800=100%.
4. We know, that x is 1800% of the output value, so we can write it down as x=1800%.
5. Now we have two simple equations:
1) 12800=100%
2) x=1800%
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:
12800/x=100%/1800%
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 1800% of 12800

12800/x=100/1800
(12800/x)*x=(100/1800)*x       - we multiply both sides of the equation by x
12800=0.055555555555556*x       - we divide both sides of the equation by (0.055555555555556) to get x
12800/0.055555555555556=x
230400=x
x=230400

now we have:
1800% of 12800=230400
