3.92 is what percent of 10.5 - 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 10.5 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 10.5, so we can write it down as 100%=10.5.
4. We know, that x% equals 3.92 of the output value, so we can write it down as x%=3.92.
5. Now we have two simple equations:
1) 100%=10.5
2) x%=3.92
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%=10.5/3.92
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.92 is what percent of 10.5

100%/x%=10.5/3.92
(100/x)*x=(10.5/3.92)*x       - we multiply both sides of the equation by x
100=2.6785714285714*x       - we divide both sides of the equation by (2.6785714285714) to get x
100/2.6785714285714=x
37.333333333333=x
x=37.333333333333

now we have:
3.92 is 37.333333333333% of 10.5
