2.49 is what percent of 21.49 - 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 21.49 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 21.49, so we can write it down as 100%=21.49.
4. We know, that x% equals 2.49 of the output value, so we can write it down as x%=2.49.
5. Now we have two simple equations:
1) 100%=21.49
2) x%=2.49
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%=21.49/2.49
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.49 is what percent of 21.49

100%/x%=21.49/2.49
(100/x)*x=(21.49/2.49)*x       - we multiply both sides of the equation by x
100=8.6305220883534*x       - we divide both sides of the equation by (8.6305220883534) to get x
100/8.6305220883534=x
11.586784550954=x
x=11.586784550954

now we have:
2.49 is 11.586784550954% of 21.49
