What is 20.6 percent of 4200 - 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 4200 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 4200 is 100%, so we can write it down as 4200=100%.
4. We know, that x is 20.6% of the output value, so we can write it down as x=20.6%.
5. Now we have two simple equations:
1) 4200=100%
2) x=20.6%
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:
4200/x=100%/20.6%
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 20.6% of 4200

4200/x=100/20.6
(4200/x)*x=(100/20.6)*x       - we multiply both sides of the equation by x
4200=4.8543689320388*x       - we divide both sides of the equation by (4.8543689320388) to get x
4200/4.8543689320388=x
865.2=x
x=865.2

now we have:
20.6% of 4200=865.2
