39.99 is what percent of 14 - 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 14 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 14, so we can write it down as 100%=14.
4. We know, that x% equals 39.99 of the output value, so we can write it down as x%=39.99.
5. Now we have two simple equations:
1) 100%=14
2) x%=39.99
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%=14/39.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 39.99 is what percent of 14

100%/x%=14/39.99
(100/x)*x=(14/39.99)*x       - we multiply both sides of the equation by x
100=0.35008752188047*x       - we divide both sides of the equation by (0.35008752188047) to get x
100/0.35008752188047=x
285.64285714286=x
x=285.64285714286

now we have:
39.99 is 285.64285714286% of 14
