27000000 is what percent of 7 - 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 7 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 7, so we can write it down as 100%=7.
4. We know, that x% equals 27000000 of the output value, so we can write it down as x%=27000000.
5. Now we have two simple equations:
1) 100%=7
2) x%=27000000
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%=7/27000000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 27000000 is what percent of 7

100%/x%=7/27000000
(100/x)*x=(7/27000000)*x       - we multiply both sides of the equation by x
100=2.5925925925926E-7*x       - we divide both sides of the equation by (2.5925925925926E-7) to get x
100/2.5925925925926E-7=x
385714285.71429=x
x=385714285.71429

now we have:
27000000 is 385714285.71429% of 7
