15.8 is what percent of 52.3 - 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 52.3 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 52.3, so we can write it down as 100%=52.3.
4. We know, that x% equals 15.8 of the output value, so we can write it down as x%=15.8.
5. Now we have two simple equations:
1) 100%=52.3
2) x%=15.8
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%=52.3/15.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.8 is what percent of 52.3

100%/x%=52.3/15.8
(100/x)*x=(52.3/15.8)*x       - we multiply both sides of the equation by x
100=3.3101265822785*x       - we divide both sides of the equation by (3.3101265822785) to get x
100/3.3101265822785=x
30.210325047801=x
x=30.210325047801

now we have:
15.8 is 30.210325047801% of 52.3
