3.31 is what percent of 9 - 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 9 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 9, so we can write it down as 100%=9.
4. We know, that x% equals 3.31 of the output value, so we can write it down as x%=3.31.
5. Now we have two simple equations:
1) 100%=9
2) x%=3.31
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%=9/3.31
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.31 is what percent of 9

100%/x%=9/3.31
(100/x)*x=(9/3.31)*x       - we multiply both sides of the equation by x
100=2.7190332326284*x       - we divide both sides of the equation by (2.7190332326284) to get x
100/2.7190332326284=x
36.777777777778=x
x=36.777777777778

now we have:
3.31 is 36.777777777778% of 9
