What is 20000000 percent of 315000000 - 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 315000000 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 315000000 is 100%, so we can write it down as 315000000=100%.
4. We know, that x is 20000000% of the output value, so we can write it down as x=20000000%.
5. Now we have two simple equations:
1) 315000000=100%
2) x=20000000%
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:
315000000/x=100%/20000000%
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 20000000% of 315000000

315000000/x=100/20000000
(315000000/x)*x=(100/20000000)*x       - we multiply both sides of the equation by x
315000000=5.0E-6*x       - we divide both sides of the equation by (5.0E-6) to get x
315000000/5.0E-6=x
63000000000000=x
x=63000000000000

now we have:
20000000% of 315000000=63000000000000
