What is 67.2 percent of 42000 - 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 42000 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 42000 is 100%, so we can write it down as 42000=100%.
4. We know, that x is 67.2% of the output value, so we can write it down as x=67.2%.
5. Now we have two simple equations:
1) 42000=100%
2) x=67.2%
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:
42000/x=100%/67.2%
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 67.2% of 42000

42000/x=100/67.2
(42000/x)*x=(100/67.2)*x       - we multiply both sides of the equation by x
42000=1.4880952380952*x       - we divide both sides of the equation by (1.4880952380952) to get x
42000/1.4880952380952=x
28224=x
x=28224

now we have:
67.2% of 42000=28224
