81.42 is what percent of 195.2 - 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 195.2 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 195.2, so we can write it down as 100%=195.2.
4. We know, that x% equals 81.42 of the output value, so we can write it down as x%=81.42.
5. Now we have two simple equations:
1) 100%=195.2
2) x%=81.42
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%=195.2/81.42
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 81.42 is what percent of 195.2

100%/x%=195.2/81.42
(100/x)*x=(195.2/81.42)*x       - we multiply both sides of the equation by x
100=2.397445345124*x       - we divide both sides of the equation by (2.397445345124) to get x
100/2.397445345124=x
41.71106557377=x
x=41.71106557377

now we have:
81.42 is 41.71106557377% of 195.2
