72 is what percent of 3508 - 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 3508 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 3508, so we can write it down as 100%=3508.
4. We know, that x% equals 72 of the output value, so we can write it down as x%=72.
5. Now we have two simple equations:
1) 100%=3508
2) x%=72
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%=3508/72
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 72 is what percent of 3508

100%/x%=3508/72
(100/x)*x=(3508/72)*x       - we multiply both sides of the equation by x
100=48.722222222222*x       - we divide both sides of the equation by (48.722222222222) to get x
100/48.722222222222=x
2.0524515393387=x
x=2.0524515393387

now we have:
72 is 2.0524515393387% of 3508
