8 is what percent of 830 - 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 830 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 830, so we can write it down as 100%=830.
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%=830
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%=830/8
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 830

100%/x%=830/8
(100/x)*x=(830/8)*x       - we multiply both sides of the equation by x
100=103.75*x       - we divide both sides of the equation by (103.75) to get x
100/103.75=x
0.96385542168675=x
x=0.96385542168675

now we have:
8 is 0.96385542168675% of 830
