38 is what percent of 31700 - 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 31700 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 31700, so we can write it down as 100%=31700.
4. We know, that x% equals 38 of the output value, so we can write it down as x%=38.
5. Now we have two simple equations:
1) 100%=31700
2) x%=38
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%=31700/38
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 38 is what percent of 31700

100%/x%=31700/38
(100/x)*x=(31700/38)*x       - we multiply both sides of the equation by x
100=834.21052631579*x       - we divide both sides of the equation by (834.21052631579) to get x
100/834.21052631579=x
0.1198738170347=x
x=0.1198738170347

now we have:
38 is 0.1198738170347% of 31700
