4 is what percent of 31300 - 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 31300 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 31300, so we can write it down as 100%=31300.
4. We know, that x% equals 4 of the output value, so we can write it down as x%=4.
5. Now we have two simple equations:
1) 100%=31300
2) x%=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%=31300/4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4 is what percent of 31300

100%/x%=31300/4
(100/x)*x=(31300/4)*x       - we multiply both sides of the equation by x
100=7825*x       - we divide both sides of the equation by (7825) to get x
100/7825=x
0.012779552715655=x
x=0.012779552715655

now we have:
4 is 0.012779552715655% of 31300
