2.63 is what percent of 21.38 - 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 21.38 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 21.38, so we can write it down as 100%=21.38.
4. We know, that x% equals 2.63 of the output value, so we can write it down as x%=2.63.
5. Now we have two simple equations:
1) 100%=21.38
2) x%=2.63
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%=21.38/2.63
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.63 is what percent of 21.38

100%/x%=21.38/2.63
(100/x)*x=(21.38/2.63)*x       - we multiply both sides of the equation by x
100=8.1292775665399*x       - we divide both sides of the equation by (8.1292775665399) to get x
100/8.1292775665399=x
12.301216089804=x
x=12.301216089804

now we have:
2.63 is 12.301216089804% of 21.38
