14 is what percent of 648 - 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 648 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 648, so we can write it down as 100%=648.
4. We know, that x% equals 14 of the output value, so we can write it down as x%=14.
5. Now we have two simple equations:
1) 100%=648
2) x%=14
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%=648/14
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 14 is what percent of 648

100%/x%=648/14
(100/x)*x=(648/14)*x       - we multiply both sides of the equation by x
100=46.285714285714*x       - we divide both sides of the equation by (46.285714285714) to get x
100/46.285714285714=x
2.1604938271605=x
x=2.1604938271605

now we have:
14 is 2.1604938271605% of 648
