What is 84.2 percent of 210000000 - 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 210000000 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 210000000 is 100%, so we can write it down as 210000000=100%.
4. We know, that x is 84.2% of the output value, so we can write it down as x=84.2%.
5. Now we have two simple equations:
1) 210000000=100%
2) x=84.2%
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:
210000000/x=100%/84.2%
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 84.2% of 210000000

210000000/x=100/84.2
(210000000/x)*x=(100/84.2)*x       - we multiply both sides of the equation by x
210000000=1.187648456057*x       - we divide both sides of the equation by (1.187648456057) to get x
210000000/1.187648456057=x
176820000=x
x=176820000

now we have:
84.2% of 210000000=176820000
