What is 1290 percent of 2500 - 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 2500 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 2500 is 100%, so we can write it down as 2500=100%.
4. We know, that x is 1290% of the output value, so we can write it down as x=1290%.
5. Now we have two simple equations:
1) 2500=100%
2) x=1290%
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:
2500/x=100%/1290%
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 1290% of 2500

2500/x=100/1290
(2500/x)*x=(100/1290)*x       - we multiply both sides of the equation by x
2500=0.077519379844961*x       - we divide both sides of the equation by (0.077519379844961) to get x
2500/0.077519379844961=x
32250=x
x=32250

now we have:
1290% of 2500=32250
