80 is what percent of 140000000 - 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 140000000 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 140000000, so we can write it down as 100%=140000000.
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%=140000000
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%=140000000/80
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 140000000

100%/x%=140000000/80
(100/x)*x=(140000000/80)*x       - we multiply both sides of the equation by x
100=1750000*x       - we divide both sides of the equation by (1750000) to get x
100/1750000=x
5.7142857142857E-5=x
x=5.7142857142857E-5

now we have:
80 is 5.7142857142857E-5% of 140000000
