8 is what percent of 151 - 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 151 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 151, so we can write it down as 100%=151.
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%=151
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%=151/8
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 151

100%/x%=151/8
(100/x)*x=(151/8)*x       - we multiply both sides of the equation by x
100=18.875*x       - we divide both sides of the equation by (18.875) to get x
100/18.875=x
5.29801324503=x
x=5.29801324503

now we have:
8 is 5.29801324503% of 151
