9.15 is what percent of 150 - 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 150 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 150, so we can write it down as 100%=150.
4. We know, that x% equals 9.15 of the output value, so we can write it down as x%=9.15.
5. Now we have two simple equations:
1) 100%=150
2) x%=9.15
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%=150/9.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9.15 is what percent of 150

100%/x%=150/9.15
(100/x)*x=(150/9.15)*x       - we multiply both sides of the equation by x
100=16.393442622951*x       - we divide both sides of the equation by (16.393442622951) to get x
100/16.393442622951=x
6.1=x
x=6.1

now we have:
9.15 is 6.1% of 150
