1.3 is what percent of 21.8 - 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 21.8 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 21.8, so we can write it down as 100%=21.8.
4. We know, that x% equals 1.3 of the output value, so we can write it down as x%=1.3.
5. Now we have two simple equations:
1) 100%=21.8
2) x%=1.3
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%=21.8/1.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.3 is what percent of 21.8

100%/x%=21.8/1.3
(100/x)*x=(21.8/1.3)*x       - we multiply both sides of the equation by x
100=16.769230769231*x       - we divide both sides of the equation by (16.769230769231) to get x
100/16.769230769231=x
5.9633027522936=x
x=5.9633027522936

now we have:
1.3 is 5.9633027522936% of 21.8
