15.97 is what percent of 28.55 - 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 28.55 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 28.55, so we can write it down as 100%=28.55.
4. We know, that x% equals 15.97 of the output value, so we can write it down as x%=15.97.
5. Now we have two simple equations:
1) 100%=28.55
2) x%=15.97
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%=28.55/15.97
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.97 is what percent of 28.55

100%/x%=28.55/15.97
(100/x)*x=(28.55/15.97)*x       - we multiply both sides of the equation by x
100=1.7877269881027*x       - we divide both sides of the equation by (1.7877269881027) to get x
100/1.7877269881027=x
55.936952714536=x
x=55.936952714536

now we have:
15.97 is 55.936952714536% of 28.55
