What is 48.5 percent of 2100000000 - 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 2100000000 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 2100000000 is 100%, so we can write it down as 2100000000=100%.
4. We know, that x is 48.5% of the output value, so we can write it down as x=48.5%.
5. Now we have two simple equations:
1) 2100000000=100%
2) x=48.5%
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:
2100000000/x=100%/48.5%
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 48.5% of 2100000000

2100000000/x=100/48.5
(2100000000/x)*x=(100/48.5)*x       - we multiply both sides of the equation by x
2100000000=2.0618556701031*x       - we divide both sides of the equation by (2.0618556701031) to get x
2100000000/2.0618556701031=x
1018500000=x
x=1018500000

now we have:
48.5% of 2100000000=1018500000
