27 is what percent of 7500000000 - 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 7500000000 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 7500000000, so we can write it down as 100%=7500000000.
4. We know, that x% equals 27 of the output value, so we can write it down as x%=27.
5. Now we have two simple equations:
1) 100%=7500000000
2) x%=27
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%=7500000000/27
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 27 is what percent of 7500000000

100%/x%=7500000000/27
(100/x)*x=(7500000000/27)*x       - we multiply both sides of the equation by x
100=277777777.77778*x       - we divide both sides of the equation by (277777777.77778) to get x
100/277777777.77778=x
3.6E-7=x
x=3.6E-7

now we have:
27 is 3.6E-7% of 7500000000
