What is 80000000 percent of 20000000 - 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 20000000 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 20000000 is 100%, so we can write it down as 20000000=100%.
4. We know, that x is 80000000% of the output value, so we can write it down as x=80000000%.
5. Now we have two simple equations:
1) 20000000=100%
2) x=80000000%
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:
20000000/x=100%/80000000%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 80000000% of 20000000

20000000/x=100/80000000
(20000000/x)*x=(100/80000000)*x       - we multiply both sides of the equation by x
20000000=1.25E-6*x       - we divide both sides of the equation by (1.25E-6) to get x
20000000/1.25E-6=x
16000000000000=x
x=16000000000000

now we have:
80000000% of 20000000=16000000000000
