8 is what percent of 2620 - 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 2620 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 2620, so we can write it down as 100%=2620.
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%=2620
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%=2620/8
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 2620

100%/x%=2620/8
(100/x)*x=(2620/8)*x       - we multiply both sides of the equation by x
100=327.5*x       - we divide both sides of the equation by (327.5) to get x
100/327.5=x
0.30534351145038=x
x=0.30534351145038

now we have:
8 is 0.30534351145038% of 2620
