7 is what percent of 80000000 - 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 80000000 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 80000000, so we can write it down as 100%=80000000.
4. We know, that x% equals 7 of the output value, so we can write it down as x%=7.
5. Now we have two simple equations:
1) 100%=80000000
2) x%=7
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%=80000000/7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7 is what percent of 80000000

100%/x%=80000000/7
(100/x)*x=(80000000/7)*x       - we multiply both sides of the equation by x
100=11428571.428571*x       - we divide both sides of the equation by (11428571.428571) to get x
100/11428571.428571=x
8.75E-6=x
x=8.75E-6

now we have:
7 is 8.75E-6% of 80000000
