What is 7.99 percent of 170 - 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 170 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 170 is 100%, so we can write it down as 170=100%.
4. We know, that x is 7.99% of the output value, so we can write it down as x=7.99%.
5. Now we have two simple equations:
1) 170=100%
2) x=7.99%
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:
170/x=100%/7.99%
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 7.99% of 170

170/x=100/7.99
(170/x)*x=(100/7.99)*x       - we multiply both sides of the equation by x
170=12.515644555695*x       - we divide both sides of the equation by (12.515644555695) to get x
170/12.515644555695=x
13.583=x
x=13.583

now we have:
7.99% of 170=13.583
