90.8 is what percent of 381.3 - 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 381.3 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 381.3, so we can write it down as 100%=381.3.
4. We know, that x% equals 90.8 of the output value, so we can write it down as x%=90.8.
5. Now we have two simple equations:
1) 100%=381.3
2) x%=90.8
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%=381.3/90.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 90.8 is what percent of 381.3

100%/x%=381.3/90.8
(100/x)*x=(381.3/90.8)*x       - we multiply both sides of the equation by x
100=4.1993392070485*x       - we divide both sides of the equation by (4.1993392070485) to get x
100/4.1993392070485=x
23.813270390768=x
x=23.813270390768

now we have:
90.8 is 23.813270390768% of 381.3
