80 is what percent of 15000000 - 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 15000000 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 15000000, so we can write it down as 100%=15000000.
4. We know, that x% equals 80 of the output value, so we can write it down as x%=80.
5. Now we have two simple equations:
1) 100%=15000000
2) x%=80
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%=15000000/80
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 80 is what percent of 15000000

100%/x%=15000000/80
(100/x)*x=(15000000/80)*x       - we multiply both sides of the equation by x
100=187500*x       - we divide both sides of the equation by (187500) to get x
100/187500=x
0.00053333333333333=x
x=0.00053333333333333

now we have:
80 is 0.00053333333333333% of 15000000
