4.31 is what percent of 31.3 - 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 31.3 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 31.3, so we can write it down as 100%=31.3.
4. We know, that x% equals 4.31 of the output value, so we can write it down as x%=4.31.
5. Now we have two simple equations:
1) 100%=31.3
2) x%=4.31
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%=31.3/4.31
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.31 is what percent of 31.3

100%/x%=31.3/4.31
(100/x)*x=(31.3/4.31)*x       - we multiply both sides of the equation by x
100=7.262180974478*x       - we divide both sides of the equation by (7.262180974478) to get x
100/7.262180974478=x
13.769968051118=x
x=13.769968051118

now we have:
4.31 is 13.769968051118% of 31.3
