1000000000 is what percent of 3 - 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 3 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 100% equals 3, so we can write it down as 100%=3.
4. We know, that x% equals 1000000000 of the output value, so we can write it down as x%=1000000000.
5. Now we have two simple equations:
1) 100%=3
2) x%=1000000000
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:
100%/x%=3/1000000000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1000000000 is what percent of 3

100%/x%=3/1000000000
(100/x)*x=(3/1000000000)*x       - we multiply both sides of the equation by x
100=3.0E-9*x       - we divide both sides of the equation by (3.0E-9) to get x
100/3.0E-9=x
33333333333.333=x
x=33333333333.333

now we have:
1000000000 is 33333333333.333% of 3
