31.48 is what percent of 15.5 - 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 15.5 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 15.5, so we can write it down as 100%=15.5.
4. We know, that x% equals 31.48 of the output value, so we can write it down as x%=31.48.
5. Now we have two simple equations:
1) 100%=15.5
2) x%=31.48
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%=15.5/31.48
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31.48 is what percent of 15.5

100%/x%=15.5/31.48
(100/x)*x=(15.5/31.48)*x       - we multiply both sides of the equation by x
100=0.49237611181703*x       - we divide both sides of the equation by (0.49237611181703) to get x
100/0.49237611181703=x
203.09677419355=x
x=203.09677419355

now we have:
31.48 is 203.09677419355% of 15.5
