72 is what percent of 5401 - 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 5401 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 5401, so we can write it down as 100%=5401.
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%=5401
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%=5401/72
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 5401

100%/x%=5401/72
(100/x)*x=(5401/72)*x       - we multiply both sides of the equation by x
100=75.013888888889*x       - we divide both sides of the equation by (75.013888888889) to get x
100/75.013888888889=x
1.3330864654694=x
x=1.3330864654694

now we have:
72 is 1.3330864654694% of 5401
