30.86 is what percent of 237.3 - 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 237.3 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 237.3, so we can write it down as 100%=237.3.
4. We know, that x% equals 30.86 of the output value, so we can write it down as x%=30.86.
5. Now we have two simple equations:
1) 100%=237.3
2) x%=30.86
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%=237.3/30.86
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 30.86 is what percent of 237.3

100%/x%=237.3/30.86
(100/x)*x=(237.3/30.86)*x       - we multiply both sides of the equation by x
100=7.6895657809462*x       - we divide both sides of the equation by (7.6895657809462) to get x
100/7.6895657809462=x
13.004635482512=x
x=13.004635482512

now we have:
30.86 is 13.004635482512% of 237.3
