What is 98 percent of 4000000000 - 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 4000000000 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 4000000000 is 100%, so we can write it down as 4000000000=100%.
4. We know, that x is 98% of the output value, so we can write it down as x=98%.
5. Now we have two simple equations:
1) 4000000000=100%
2) x=98%
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:
4000000000/x=100%/98%
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 98% of 4000000000

4000000000/x=100/98
(4000000000/x)*x=(100/98)*x       - we multiply both sides of the equation by x
4000000000=1.0204081632653*x       - we divide both sides of the equation by (1.0204081632653) to get x
4000000000/1.0204081632653=x
3920000000=x
x=3920000000

now we have:
98% of 4000000000=3920000000
