20 is what percent of 658000 - 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 658000 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 658000, so we can write it down as 100%=658000.
4. We know, that x% equals 20 of the output value, so we can write it down as x%=20.
5. Now we have two simple equations:
1) 100%=658000
2) x%=20
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%=658000/20
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20 is what percent of 658000

100%/x%=658000/20
(100/x)*x=(658000/20)*x       - we multiply both sides of the equation by x
100=32900*x       - we divide both sides of the equation by (32900) to get x
100/32900=x
0.0030395136778116=x
x=0.0030395136778116

now we have:
20 is 0.0030395136778116% of 658000
