7.99 is what percent of 17 - 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 17 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 17, so we can write it down as 100%=17.
4. We know, that x% equals 7.99 of the output value, so we can write it down as x%=7.99.
5. Now we have two simple equations:
1) 100%=17
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:
100%/x%=17/7.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.99 is what percent of 17

100%/x%=17/7.99
(100/x)*x=(17/7.99)*x       - we multiply both sides of the equation by x
100=2.1276595744681*x       - we divide both sides of the equation by (2.1276595744681) to get x
100/2.1276595744681=x
47=x
x=47

now we have:
7.99 is 47% of 17
