79.92 is what percent of 99.99 - 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 99.99 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 99.99, so we can write it down as 100%=99.99.
4. We know, that x% equals 79.92 of the output value, so we can write it down as x%=79.92.
5. Now we have two simple equations:
1) 100%=99.99
2) x%=79.92
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%=99.99/79.92
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 79.92 is what percent of 99.99

100%/x%=99.99/79.92
(100/x)*x=(99.99/79.92)*x       - we multiply both sides of the equation by x
100=1.2511261261261*x       - we divide both sides of the equation by (1.2511261261261) to get x
100/1.2511261261261=x
79.92799279928=x
x=79.92799279928

now we have:
79.92 is 79.92799279928% of 99.99
