What is 28.99 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 15 is 100%, so we can write it down as 15=100%.
4. We know, that x is 28.99% of the output value, so we can write it down as x=28.99%.
5. Now we have two simple equations:
1) 15=100%
2) x=28.99%
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:
15/x=100%/28.99%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 28.99% of 15

15/x=100/28.99
(15/x)*x=(100/28.99)*x       - we multiply both sides of the equation by x
15=3.4494653328734*x       - we divide both sides of the equation by (3.4494653328734) to get x
15/3.4494653328734=x
4.3485=x
x=4.3485

now we have:
28.99% of 15=4.3485
