67.99 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 67.99 of the output value, so we can write it down as x%=67.99.
5. Now we have two simple equations:
1) 100%=99.99
2) x%=67.99
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%=99.99/67.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 67.99 is what percent of 99.99

100%/x%=99.99/67.99
(100/x)*x=(99.99/67.99)*x       - we multiply both sides of the equation by x
100=1.4706574496249*x       - we divide both sides of the equation by (1.4706574496249) to get x
100/1.4706574496249=x
67.996799679968=x
x=67.996799679968

now we have:
67.99 is 67.996799679968% of 99.99
