2 is what percent of 3120 - 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 3120 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 3120, so we can write it down as 100%=3120.
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%=3120
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%=3120/2
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 3120

100%/x%=3120/2
(100/x)*x=(3120/2)*x       - we multiply both sides of the equation by x
100=1560*x       - we divide both sides of the equation by (1560) to get x
100/1560=x
0.064102564102564=x
x=0.064102564102564

now we have:
2 is 0.064102564102564% of 3120
