0.13 is what percent of 21.97 - 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 21.97 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 21.97, so we can write it down as 100%=21.97.
4. We know, that x% equals 0.13 of the output value, so we can write it down as x%=0.13.
5. Now we have two simple equations:
1) 100%=21.97
2) x%=0.13
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%=21.97/0.13
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.13 is what percent of 21.97

100%/x%=21.97/0.13
(100/x)*x=(21.97/0.13)*x       - we multiply both sides of the equation by x
100=169*x       - we divide both sides of the equation by (169) to get x
100/169=x
0.59171597633136=x
x=0.59171597633136

now we have:
0.13 is 0.59171597633136% of 21.97
