15.43 is what percent of 216 - 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 216 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 216, so we can write it down as 100%=216.
4. We know, that x% equals 15.43 of the output value, so we can write it down as x%=15.43.
5. Now we have two simple equations:
1) 100%=216
2) x%=15.43
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%=216/15.43
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.43 is what percent of 216

100%/x%=216/15.43
(100/x)*x=(216/15.43)*x       - we multiply both sides of the equation by x
100=13.99870382372*x       - we divide both sides of the equation by (13.99870382372) to get x
100/13.99870382372=x
7.1435185185185=x
x=7.1435185185185

now we have:
15.43 is 7.1435185185185% of 216
