What is 490000 percent of 4200000 - 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 4200000 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 4200000 is 100%, so we can write it down as 4200000=100%.
4. We know, that x is 490000% of the output value, so we can write it down as x=490000%.
5. Now we have two simple equations:
1) 4200000=100%
2) x=490000%
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:
4200000/x=100%/490000%
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 490000% of 4200000

4200000/x=100/490000
(4200000/x)*x=(100/490000)*x       - we multiply both sides of the equation by x
4200000=0.00020408163265306*x       - we divide both sides of the equation by (0.00020408163265306) to get x
4200000/0.00020408163265306=x
20580000000=x
x=20580000000

now we have:
490000% of 4200000=20580000000
