72 is what percent of 4320 - 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 4320 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 4320, so we can write it down as 100%=4320.
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%=4320
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%=4320/72
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 4320

100%/x%=4320/72
(100/x)*x=(4320/72)*x       - we multiply both sides of the equation by x
100=60*x       - we divide both sides of the equation by (60) to get x
100/60=x
1.6666666666667=x
x=1.6666666666667

now we have:
72 is 1.6666666666667% of 4320
