90.25 is what percent of 105 - 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 105 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 105, so we can write it down as 100%=105.
4. We know, that x% equals 90.25 of the output value, so we can write it down as x%=90.25.
5. Now we have two simple equations:
1) 100%=105
2) x%=90.25
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%=105/90.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 90.25 is what percent of 105

100%/x%=105/90.25
(100/x)*x=(105/90.25)*x       - we multiply both sides of the equation by x
100=1.1634349030471*x       - we divide both sides of the equation by (1.1634349030471) to get x
100/1.1634349030471=x
85.952380952381=x
x=85.952380952381

now we have:
90.25 is 85.952380952381% of 105
