432.8 is what percent of 15 - 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 15 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 15, so we can write it down as 100%=15.
4. We know, that x% equals 432.8 of the output value, so we can write it down as x%=432.8.
5. Now we have two simple equations:
1) 100%=15
2) x%=432.8
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%=15/432.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 432.8 is what percent of 15

100%/x%=15/432.8
(100/x)*x=(15/432.8)*x       - we multiply both sides of the equation by x
100=0.034658040665434*x       - we divide both sides of the equation by (0.034658040665434) to get x
100/0.034658040665434=x
2885.3333333333=x
x=2885.3333333333

now we have:
432.8 is 2885.3333333333% of 15
