4.5 is what percent of 1260000000 - 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 1260000000 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 1260000000, so we can write it down as 100%=1260000000.
4. We know, that x% equals 4.5 of the output value, so we can write it down as x%=4.5.
5. Now we have two simple equations:
1) 100%=1260000000
2) x%=4.5
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:
100%/x%=1260000000/4.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.5 is what percent of 1260000000

100%/x%=1260000000/4.5
(100/x)*x=(1260000000/4.5)*x       - we multiply both sides of the equation by x
100=280000000*x       - we divide both sides of the equation by (280000000) to get x
100/280000000=x
3.5714285714286E-7=x
x=3.5714285714286E-7

now we have:
4.5 is 3.5714285714286E-7% of 1260000000
