What is 15.99 percent of 109.99 - 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 109.99 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 109.99 is 100%, so we can write it down as 109.99=100%.
4. We know, that x is 15.99% of the output value, so we can write it down as x=15.99%.
5. Now we have two simple equations:
1) 109.99=100%
2) x=15.99%
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:
109.99/x=100%/15.99%
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 15.99% of 109.99

109.99/x=100/15.99
(109.99/x)*x=(100/15.99)*x       - we multiply both sides of the equation by x
109.99=6.2539086929331*x       - we divide both sides of the equation by (6.2539086929331) to get x
109.99/6.2539086929331=x
17.587401=x
x=17.587401

now we have:
15.99% of 109.99=17.587401
