31.3 is what percent of 234 - 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 234 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 234, so we can write it down as 100%=234.
4. We know, that x% equals 31.3 of the output value, so we can write it down as x%=31.3.
5. Now we have two simple equations:
1) 100%=234
2) x%=31.3
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%=234/31.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31.3 is what percent of 234

100%/x%=234/31.3
(100/x)*x=(234/31.3)*x       - we multiply both sides of the equation by x
100=7.4760383386581*x       - we divide both sides of the equation by (7.4760383386581) to get x
100/7.4760383386581=x
13.376068376068=x
x=13.376068376068

now we have:
31.3 is 13.376068376068% of 234
