1639 is what percent of 8506 - 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 8506 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 8506, so we can write it down as 100%=8506.
4. We know, that x% equals 1639 of the output value, so we can write it down as x%=1639.
5. Now we have two simple equations:
1) 100%=8506
2) x%=1639
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%=8506/1639
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1639 is what percent of 8506

100%/x%=8506/1639
(100/x)*x=(8506/1639)*x       - we multiply both sides of the equation by x
100=5.189749847468*x       - we divide both sides of the equation by (5.189749847468) to get x
100/5.189749847468=x
19.268751469551=x
x=19.268751469551

now we have:
1639 is 19.268751469551% of 8506
