8 is what percent of 1617 - 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 1617 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 1617, so we can write it down as 100%=1617.
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%=1617
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%=1617/8
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 1617

100%/x%=1617/8
(100/x)*x=(1617/8)*x       - we multiply both sides of the equation by x
100=202.125*x       - we divide both sides of the equation by (202.125) to get x
100/202.125=x
0.49474335188621=x
x=0.49474335188621

now we have:
8 is 0.49474335188621% of 1617
