81.3 is what percent of 270.1 - 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 270.1 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 270.1, so we can write it down as 100%=270.1.
4. We know, that x% equals 81.3 of the output value, so we can write it down as x%=81.3.
5. Now we have two simple equations:
1) 100%=270.1
2) x%=81.3
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%=270.1/81.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 81.3 is what percent of 270.1

100%/x%=270.1/81.3
(100/x)*x=(270.1/81.3)*x       - we multiply both sides of the equation by x
100=3.3222632226322*x       - we divide both sides of the equation by (3.3222632226322) to get x
100/3.3222632226322=x
30.099962976675=x
x=30.099962976675

now we have:
81.3 is 30.099962976675% of 270.1
