94.2 is what percent of 405 - 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 405 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 405, so we can write it down as 100%=405.
4. We know, that x% equals 94.2 of the output value, so we can write it down as x%=94.2.
5. Now we have two simple equations:
1) 100%=405
2) x%=94.2
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%=405/94.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 94.2 is what percent of 405

100%/x%=405/94.2
(100/x)*x=(405/94.2)*x       - we multiply both sides of the equation by x
100=4.2993630573248*x       - we divide both sides of the equation by (4.2993630573248) to get x
100/4.2993630573248=x
23.259259259259=x
x=23.259259259259

now we have:
94.2 is 23.259259259259% of 405
