15 is what percent of 224.99 - 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 224.99 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 224.99, so we can write it down as 100%=224.99.
4. We know, that x% equals 15 of the output value, so we can write it down as x%=15.
5. Now we have two simple equations:
1) 100%=224.99
2) x%=15
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%=224.99/15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15 is what percent of 224.99

100%/x%=224.99/15
(100/x)*x=(224.99/15)*x       - we multiply both sides of the equation by x
100=14.999333333333*x       - we divide both sides of the equation by (14.999333333333) to get x
100/14.999333333333=x
6.6669629761323=x
x=6.6669629761323

now we have:
15 is 6.6669629761323% of 224.99
