30 is what percent of 730000000 - 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 730000000 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 730000000, so we can write it down as 100%=730000000.
4. We know, that x% equals 30 of the output value, so we can write it down as x%=30.
5. Now we have two simple equations:
1) 100%=730000000
2) x%=30
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%=730000000/30
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 30 is what percent of 730000000

100%/x%=730000000/30
(100/x)*x=(730000000/30)*x       - we multiply both sides of the equation by x
100=24333333.333333*x       - we divide both sides of the equation by (24333333.333333) to get x
100/24333333.333333=x
4.1095890410959E-6=x
x=4.1095890410959E-6

now we have:
30 is 4.1095890410959E-6% of 730000000
