81.72 is what percent of 600 - 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 600 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 600, so we can write it down as 100%=600.
4. We know, that x% equals 81.72 of the output value, so we can write it down as x%=81.72.
5. Now we have two simple equations:
1) 100%=600
2) x%=81.72
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%=600/81.72
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 81.72 is what percent of 600

100%/x%=600/81.72
(100/x)*x=(600/81.72)*x       - we multiply both sides of the equation by x
100=7.3421439060206*x       - we divide both sides of the equation by (7.3421439060206) to get x
100/7.3421439060206=x
13.62=x
x=13.62

now we have:
81.72 is 13.62% of 600
