3.97 is what percent of 323.1 - 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 323.1 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 323.1, so we can write it down as 100%=323.1.
4. We know, that x% equals 3.97 of the output value, so we can write it down as x%=3.97.
5. Now we have two simple equations:
1) 100%=323.1
2) x%=3.97
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%=323.1/3.97
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.97 is what percent of 323.1

100%/x%=323.1/3.97
(100/x)*x=(323.1/3.97)*x       - we multiply both sides of the equation by x
100=81.385390428212*x       - we divide both sides of the equation by (81.385390428212) to get x
100/81.385390428212=x
1.2287217579697=x
x=1.2287217579697

now we have:
3.97 is 1.2287217579697% of 323.1
