14.7 is what percent of 399 - 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 399 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 399, so we can write it down as 100%=399.
4. We know, that x% equals 14.7 of the output value, so we can write it down as x%=14.7.
5. Now we have two simple equations:
1) 100%=399
2) x%=14.7
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%=399/14.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 14.7 is what percent of 399

100%/x%=399/14.7
(100/x)*x=(399/14.7)*x       - we multiply both sides of the equation by x
100=27.142857142857*x       - we divide both sides of the equation by (27.142857142857) to get x
100/27.142857142857=x
3.6842105263158=x
x=3.6842105263158

now we have:
14.7 is 3.6842105263158% of 399
