13.64 is what percent of 30 - 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 30 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 30, so we can write it down as 100%=30.
4. We know, that x% equals 13.64 of the output value, so we can write it down as x%=13.64.
5. Now we have two simple equations:
1) 100%=30
2) x%=13.64
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%=30/13.64
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.64 is what percent of 30

100%/x%=30/13.64
(100/x)*x=(30/13.64)*x       - we multiply both sides of the equation by x
100=2.1994134897361*x       - we divide both sides of the equation by (2.1994134897361) to get x
100/2.1994134897361=x
45.466666666667=x
x=45.466666666667

now we have:
13.64 is 45.466666666667% of 30
