8.4 is what percent of 80000 - 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 80000 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 80000, so we can write it down as 100%=80000.
4. We know, that x% equals 8.4 of the output value, so we can write it down as x%=8.4.
5. Now we have two simple equations:
1) 100%=80000
2) x%=8.4
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%=80000/8.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.4 is what percent of 80000

100%/x%=80000/8.4
(100/x)*x=(80000/8.4)*x       - we multiply both sides of the equation by x
100=9523.8095238095*x       - we divide both sides of the equation by (9523.8095238095) to get x
100/9523.8095238095=x
0.0105=x
x=0.0105

now we have:
8.4 is 0.0105% of 80000
