2 is what percent of 78880 - 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 78880 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 78880, so we can write it down as 100%=78880.
4. We know, that x% equals 2 of the output value, so we can write it down as x%=2.
5. Now we have two simple equations:
1) 100%=78880
2) x%=2
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%=78880/2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2 is what percent of 78880

100%/x%=78880/2
(100/x)*x=(78880/2)*x       - we multiply both sides of the equation by x
100=39440*x       - we divide both sides of the equation by (39440) to get x
100/39440=x
0.0025354969574037=x
x=0.0025354969574037

now we have:
2 is 0.0025354969574037% of 78880
