2 is what percent of 7871 - 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 7871 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 7871, so we can write it down as 100%=7871.
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%=7871
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%=7871/2
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 7871

100%/x%=7871/2
(100/x)*x=(7871/2)*x       - we multiply both sides of the equation by x
100=3935.5*x       - we divide both sides of the equation by (3935.5) to get x
100/3935.5=x
0.025409731927328=x
x=0.025409731927328

now we have:
2 is 0.025409731927328% of 7871
