3 is what percent of 27.31 - 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 27.31 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 27.31, so we can write it down as 100%=27.31.
4. We know, that x% equals 3 of the output value, so we can write it down as x%=3.
5. Now we have two simple equations:
1) 100%=27.31
2) x%=3
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%=27.31/3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3 is what percent of 27.31

100%/x%=27.31/3
(100/x)*x=(27.31/3)*x       - we multiply both sides of the equation by x
100=9.1033333333333*x       - we divide both sides of the equation by (9.1033333333333) to get x
100/9.1033333333333=x
10.984987184182=x
x=10.984987184182

now we have:
3 is 10.984987184182% of 27.31
