7.2 is what percent of 31000 - 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 31000 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 31000, so we can write it down as 100%=31000.
4. We know, that x% equals 7.2 of the output value, so we can write it down as x%=7.2.
5. Now we have two simple equations:
1) 100%=31000
2) x%=7.2
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%=31000/7.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.2 is what percent of 31000

100%/x%=31000/7.2
(100/x)*x=(31000/7.2)*x       - we multiply both sides of the equation by x
100=4305.5555555556*x       - we divide both sides of the equation by (4305.5555555556) to get x
100/4305.5555555556=x
0.023225806451613=x
x=0.023225806451613

now we have:
7.2 is 0.023225806451613% of 31000
