What is 4200 percent of 6.89 - 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 6.89 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 6.89 is 100%, so we can write it down as 6.89=100%.
4. We know, that x is 4200% of the output value, so we can write it down as x=4200%.
5. Now we have two simple equations:
1) 6.89=100%
2) x=4200%
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:
6.89/x=100%/4200%
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 4200% of 6.89

6.89/x=100/4200
(6.89/x)*x=(100/4200)*x       - we multiply both sides of the equation by x
6.89=0.023809523809524*x       - we divide both sides of the equation by (0.023809523809524) to get x
6.89/0.023809523809524=x
289.38=x
x=289.38

now we have:
4200% of 6.89=289.38
