138701.39 is what percent of 21.5 - 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 21.5 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 21.5, so we can write it down as 100%=21.5.
4. We know, that x% equals 138701.39 of the output value, so we can write it down as x%=138701.39.
5. Now we have two simple equations:
1) 100%=21.5
2) x%=138701.39
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%=21.5/138701.39
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 138701.39 is what percent of 21.5

100%/x%=21.5/138701.39
(100/x)*x=(21.5/138701.39)*x       - we multiply both sides of the equation by x
100=0.00015500926126263*x       - we divide both sides of the equation by (0.00015500926126263) to get x
100/0.00015500926126263=x
645122.74418605=x
x=645122.74418605

now we have:
138701.39 is 645122.74418605% of 21.5
