72 is what percent of 485 - 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 485 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 485, so we can write it down as 100%=485.
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%=485
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%=485/72
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 485

100%/x%=485/72
(100/x)*x=(485/72)*x       - we multiply both sides of the equation by x
100=6.7361111111111*x       - we divide both sides of the equation by (6.7361111111111) to get x
100/6.7361111111111=x
14.845360824742=x
x=14.845360824742

now we have:
72 is 14.845360824742% of 485
