8 is what percent of 918 - 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 918 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 918, so we can write it down as 100%=918.
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%=918
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%=918/8
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 918

100%/x%=918/8
(100/x)*x=(918/8)*x       - we multiply both sides of the equation by x
100=114.75*x       - we divide both sides of the equation by (114.75) to get x
100/114.75=x
0.87145969498911=x
x=0.87145969498911

now we have:
8 is 0.87145969498911% of 918
