7.29 is what percent of 18000000 - 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 18000000 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 18000000, so we can write it down as 100%=18000000.
4. We know, that x% equals 7.29 of the output value, so we can write it down as x%=7.29.
5. Now we have two simple equations:
1) 100%=18000000
2) x%=7.29
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%=18000000/7.29
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.29 is what percent of 18000000

100%/x%=18000000/7.29
(100/x)*x=(18000000/7.29)*x       - we multiply both sides of the equation by x
100=2469135.8024691*x       - we divide both sides of the equation by (2469135.8024691) to get x
100/2469135.8024691=x
4.05E-5=x
x=4.05E-5

now we have:
7.29 is 4.05E-5% of 18000000
