What is 80000 percent of 500 - 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 500 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 500 is 100%, so we can write it down as 500=100%.
4. We know, that x is 80000% of the output value, so we can write it down as x=80000%.
5. Now we have two simple equations:
1) 500=100%
2) x=80000%
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:
500/x=100%/80000%
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 80000% of 500

500/x=100/80000
(500/x)*x=(100/80000)*x       - we multiply both sides of the equation by x
500=0.00125*x       - we divide both sides of the equation by (0.00125) to get x
500/0.00125=x
400000=x
x=400000

now we have:
80000% of 500=400000
