2 is what percent of 157920 - 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 157920 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 157920, so we can write it down as 100%=157920.
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%=157920
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%=157920/2
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 157920

100%/x%=157920/2
(100/x)*x=(157920/2)*x       - we multiply both sides of the equation by x
100=78960*x       - we divide both sides of the equation by (78960) to get x
100/78960=x
0.0012664640324215=x
x=0.0012664640324215

now we have:
2 is 0.0012664640324215% of 157920
