17.99 is what percent of 79.99 - 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 79.99 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 100% equals 79.99, so we can write it down as 100%=79.99.
4. We know, that x% equals 17.99 of the output value, so we can write it down as x%=17.99.
5. Now we have two simple equations:
1) 100%=79.99
2) x%=17.99
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%=79.99/17.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.99 is what percent of 79.99

100%/x%=79.99/17.99
(100/x)*x=(79.99/17.99)*x       - we multiply both sides of the equation by x
100=4.4463590883824*x       - we divide both sides of the equation by (4.4463590883824) to get x
100/4.4463590883824=x
22.490311288911=x
x=22.490311288911

now we have:
17.99 is 22.490311288911% of 79.99
