235.5 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 235.5 of the output value, so we can write it down as x%=235.5.
5. Now we have two simple equations:
1) 100%=405
2) x%=235.5
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%=405/235.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 235.5 is what percent of 405

100%/x%=405/235.5
(100/x)*x=(405/235.5)*x       - we multiply both sides of the equation by x
100=1.7197452229299*x       - we divide both sides of the equation by (1.7197452229299) to get x
100/1.7197452229299=x
58.148148148148=x
x=58.148148148148

now we have:
235.5 is 58.148148148148% of 405
