What is 310000000 percent of 680000000 - 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 680000000 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 680000000 is 100%, so we can write it down as 680000000=100%.
4. We know, that x is 310000000% of the output value, so we can write it down as x=310000000%.
5. Now we have two simple equations:
1) 680000000=100%
2) x=310000000%
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:
680000000/x=100%/310000000%
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 310000000% of 680000000

680000000/x=100/310000000
(680000000/x)*x=(100/310000000)*x       - we multiply both sides of the equation by x
680000000=3.2258064516129E-7*x       - we divide both sides of the equation by (3.2258064516129E-7) to get x
680000000/3.2258064516129E-7=x
2.108E+15=x
x=2.108E+15

now we have:
310000000% of 680000000=2.108E+15
