31.4 is what percent of 27.5 - 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 27.5 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 27.5, so we can write it down as 100%=27.5.
4. We know, that x% equals 31.4 of the output value, so we can write it down as x%=31.4.
5. Now we have two simple equations:
1) 100%=27.5
2) x%=31.4
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%=27.5/31.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31.4 is what percent of 27.5

100%/x%=27.5/31.4
(100/x)*x=(27.5/31.4)*x       - we multiply both sides of the equation by x
100=0.87579617834395*x       - we divide both sides of the equation by (0.87579617834395) to get x
100/0.87579617834395=x
114.18181818182=x
x=114.18181818182

now we have:
31.4 is 114.18181818182% of 27.5
