What is 250 percent of 20420 - 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 20420 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 20420 is 100%, so we can write it down as 20420=100%.
4. We know, that x is 250% of the output value, so we can write it down as x=250%.
5. Now we have two simple equations:
1) 20420=100%
2) x=250%
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:
20420/x=100%/250%
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 250% of 20420

20420/x=100/250
(20420/x)*x=(100/250)*x       - we multiply both sides of the equation by x
20420=0.4*x       - we divide both sides of the equation by (0.4) to get x
20420/0.4=x
51050=x
x=51050

now we have:
250% of 20420=51050
