5.09 is what percent of 75.72 - 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 75.72 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 75.72, so we can write it down as 100%=75.72.
4. We know, that x% equals 5.09 of the output value, so we can write it down as x%=5.09.
5. Now we have two simple equations:
1) 100%=75.72
2) x%=5.09
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%=75.72/5.09
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5.09 is what percent of 75.72

100%/x%=75.72/5.09
(100/x)*x=(75.72/5.09)*x       - we multiply both sides of the equation by x
100=14.876227897839*x       - we divide both sides of the equation by (14.876227897839) to get x
100/14.876227897839=x
6.7221341785526=x
x=6.7221341785526

now we have:
5.09 is 6.7221341785526% of 75.72
