79990 is what percent of 2 - 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 2 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 2, so we can write it down as 100%=2.
4. We know, that x% equals 79990 of the output value, so we can write it down as x%=79990.
5. Now we have two simple equations:
1) 100%=2
2) x%=79990
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%=2/79990
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 79990 is what percent of 2

100%/x%=2/79990
(100/x)*x=(2/79990)*x       - we multiply both sides of the equation by x
100=2.5003125390674E-5*x       - we divide both sides of the equation by (2.5003125390674E-5) to get x
100/2.5003125390674E-5=x
3999500=x
x=3999500

now we have:
79990 is 3999500% of 2
