15.83 is what percent of 64.17 - 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 64.17 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 64.17, so we can write it down as 100%=64.17.
4. We know, that x% equals 15.83 of the output value, so we can write it down as x%=15.83.
5. Now we have two simple equations:
1) 100%=64.17
2) x%=15.83
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%=64.17/15.83
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.83 is what percent of 64.17

100%/x%=64.17/15.83
(100/x)*x=(64.17/15.83)*x       - we multiply both sides of the equation by x
100=4.0536955148452*x       - we divide both sides of the equation by (4.0536955148452) to get x
100/4.0536955148452=x
24.668848371513=x
x=24.668848371513

now we have:
15.83 is 24.668848371513% of 64.17
