2.9 is what percent of 13.6 - 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 13.6 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 13.6, so we can write it down as 100%=13.6.
4. We know, that x% equals 2.9 of the output value, so we can write it down as x%=2.9.
5. Now we have two simple equations:
1) 100%=13.6
2) x%=2.9
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%=13.6/2.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.9 is what percent of 13.6

100%/x%=13.6/2.9
(100/x)*x=(13.6/2.9)*x       - we multiply both sides of the equation by x
100=4.6896551724138*x       - we divide both sides of the equation by (4.6896551724138) to get x
100/4.6896551724138=x
21.323529411765=x
x=21.323529411765

now we have:
2.9 is 21.323529411765% of 13.6
