8 is what percent of 1861 - 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 1861 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 1861, so we can write it down as 100%=1861.
4. We know, that x% equals 8 of the output value, so we can write it down as x%=8.
5. Now we have two simple equations:
1) 100%=1861
2) x%=8
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%=1861/8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8 is what percent of 1861

100%/x%=1861/8
(100/x)*x=(1861/8)*x       - we multiply both sides of the equation by x
100=232.625*x       - we divide both sides of the equation by (232.625) to get x
100/232.625=x
0.42987641053197=x
x=0.42987641053197

now we have:
8 is 0.42987641053197% of 1861
