What is 420 percent of 17200 - 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 17200 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 17200 is 100%, so we can write it down as 17200=100%.
4. We know, that x is 420% of the output value, so we can write it down as x=420%.
5. Now we have two simple equations:
1) 17200=100%
2) x=420%
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:
17200/x=100%/420%
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 420% of 17200

17200/x=100/420
(17200/x)*x=(100/420)*x       - we multiply both sides of the equation by x
17200=0.23809523809524*x       - we divide both sides of the equation by (0.23809523809524) to get x
17200/0.23809523809524=x
72240=x
x=72240

now we have:
420% of 17200=72240
