15 is what percent of 119.69 - 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 119.69 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 119.69, so we can write it down as 100%=119.69.
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%=119.69
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%=119.69/15
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 119.69

100%/x%=119.69/15
(100/x)*x=(119.69/15)*x       - we multiply both sides of the equation by x
100=7.9793333333333*x       - we divide both sides of the equation by (7.9793333333333) to get x
100/7.9793333333333=x
12.532375302866=x
x=12.532375302866

now we have:
15 is 12.532375302866% of 119.69
