20 is what percent of 13.03 - 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 13.03 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 13.03, so we can write it down as 100%=13.03.
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%=13.03
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%=13.03/20
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 13.03

100%/x%=13.03/20
(100/x)*x=(13.03/20)*x       - we multiply both sides of the equation by x
100=0.6515*x       - we divide both sides of the equation by (0.6515) to get x
100/0.6515=x
153.49194167306=x
x=153.49194167306

now we have:
20 is 153.49194167306% of 13.03
